The MSM66509/66P509 includes a 16-bit CPU, ROM, RAM, a 10-bit A/D converter, serial ports, flexible timers, pulse-width modulator (PWM), and I/O ports. FEATURES • Program memory space : 64K bytes Internal ROM : 64K bytes • Data memory space : 64K bytes Internal RAM : 2K bytes • High-speed execution Minimum instruction execution time : 125nsec @ 32MHz • Powerful instruction set : Instruction set superior in orthogonal matrix 8/16-bit data transfer instructions 8/16-bit arithmetic instructions Multiplication and division operation instructions Bit manipulation instructions Bit logic instructions ROM table reference instructions • Abundant addressing modes : Register addressing Page addressing Pointing register indirect addressing Stack addressing Immediate addressing • I/O port Analog input port : 1 port ¥ 16 bits Input-output port : 11 ports ¥ 8 bits, 1 port ¥ 4 bits (Input/output setting available in bit unit) • Flexible timers Free run counters : 19-bit ¥ 1, 16-bit ¥ 1 19-bit CAP with a divider :4 16-bit double buffer RTO :6 16-bit PWM/RTO :2 16-bit CAP/RTO :2 • 8-bit general timer :1 8-bit event counter :1 • 16-bit PWM :6 Input clock divider :4 • Serial ports UART mode with BRG :1 Synchronous/UART switchable mode with BRG :1 • 10-bit A/D converter : 16 channels 1/24 ¡ Semiconductor MSM66509/66P509 PIN DESCRIPTION (Continued) Symbol AI0-AI15 AVDD VREF AGND OSC0 OSC1 ALE PSEN OE NMI RES EA VDD GND Type I I I I I O O O I I I I I I Description Analog signal input pin for A/D converter Power supply input pin for A/D converter Reference voltage input pin for A/D converter GND input pin for A/D converter Basic clock oscillation pin Basic clock oscillation pin Timing pulse output pin to latch the lower 8 bits of the address output from port 0 when the CPU accesses the external memory Strobe pulse output pin to fetch to external program memory When P0, P1, P7.4-P7.7, and P8-P11 are in an output state and OE pin is "H" level, the ports go to a high-impedance state. When P0, P1, P7.4-P7.7, and P8-P11 are in an output state and OE pin is "L" level, the ports output "H" or "L" level. However, when P0, P1, P7.4-P7.7, and P8-P11 are in an input state, these ports are not under the influence of OE pin. Nonmaskable interrupt request input pin Low-active RESET input pin Normally set to "H" level. If set to "L" level, the program memory goes into external access mode and accesses external program memory Power supply pin Ground pin 6/24 6 Page ¡ Semiconductor MSM66509/66P509 SFR (Continued) Address [H] 00C0 00C1 00C2 00C3 00C4 00C5 00C6 00C7 00C8 00C9I 00CA 00CB 00CC 00CD 00CE 00CFI 00D0I 00D1I 00D2 00D4 00D5 00D6 00D7 00D8I 00D9I 00DAI 00DBI 00DCI 00DDI 00DEI 00DFI 00E0 00E1 00E2 00E3 00E4 00E5 00E6 00E7 00E8 00E9 00EA 00EB 00ECI 00EDI 00EEI 00EFI Name TMR4 buffer register TMR5 buffer register TMR6 buffer register TMR7 buffer register Timer control register Timer counter 0 lower 3 bits Timer counter 0 Timer counter 1 Capture control register 0 Capture control register 1 Event control register TMR mode register Timer register 12 Timer register 13 Event dividing counter 0 Event dividing counter 1 Event dividing counter 2 Event dividing counter 3 EVDV0 buffer register EVDV1 buffer register EVDV2 buffer register EVDV3 buffer register A/DC result register 0 A/DC result register 1 A/DC result register 2 A/DC result register 3 A/DC result register 4 A/DC result register 5 A/DC result register 6 A/DC result register 7 A/DC result register 8 A/DC result register 9 A/DC result register lower 0 A/DC result register lower 1 A/DC result register lower 2 A/D interrupt control register A/DC control register L A/DC control register H Symbol TMR4BF TMR5BF TMR6BF TMR7BF TMCON TM0L TM0 TM1 CAPCON0 CAPCON1 EVNTCONL EVNTCONH TMRMODE TMR12 TMR13 EVDV0 EVDV1 EVDV2 EVDV3 EVDV0BF EVDV1BF EVDV2BF EVDV3BF ADCR0 ADCR1 ADCR2 ADCR3 ADCR4 ADCR5 ADCR6 ADCR7 ADCR8 ADCR9 LADCR0 LADCR1 LADCR2 ADINTCON ADCONL ADCONH R/W R/W 8/16-bit Operation 8/16 8 8/16 8 Reset 00 00 00 00 00 00 00 00 00 1F 00 00 00 00 00 F0 88 88 00 0000 16 0000 C0 C0 C0 8/16 C0 C0 C0 C0 C0 8/16 R Undefined 8 R/W F0 80 80 Note: A I mark in the address column indicates that there is a bit that does not exist in the register. 8/16 means a special word manipulation.
