from HIRC and HXT
– Supports clock on-the-fly switch
– Supports clock failure detection for high/low speed external crystal oscillator
– Supports auto clock switch once clock failure detected
– Supports exception (NMI) generated once a clock failure detected
– Supports divided clock output
GPIO
– Four I/O modes
– TTL/Schmitt trigger input selectable
– I/O pin configured as interrupt source with edge/level trigger setting
– Supports high driver and high sink current I/O (up to 20 mA at 5V)
– Supports software selectable slew rate control
– Supports up to 52/38/22 GPIOs for LQFP64/48 and QFN33 respectively
Timer
– Supports 4 sets of 32-bit timers with 24-bit up-timer and one 8-bit pre-scale counter
– Independent clock source for each timer
– Provides one-shot, periodic, toggle and continuous counting operation modes
– Supports event counting function to count the event from external pin
– Supports input capture function to capture or reset counter value
– Supports chip wake-up from Idle/Power-down mode if a timer interrupt signal is
generated
– Support Timer0 ~ Timer3 time-out interrupt signal or capture interrupt signal to trigger
BPWM, PWM, ADC and PDMA function
– Supports Inter-Timer trigger mode
Watchdog Timer
– Supports multiple clock sources from LIRC (default selection), HCLK/2048 and LXT
– Supports 8 selections of time-out period (1.6ms ~ 26.0sec for LIRC)
– Supports wake up from Power-down or Idle mode
– Supports Interrupt or reset selectable on watchdog time-out
Window Watchdog Timer
– Supports multiple clock sources from HCLK/2048 (default selection) and LIRC
– Supports Window set by 6-bit counter with 11-bit prescale
– Supports Interrupt
BPWM/Capture
– Supports maximum clock frequency up to 100MHz
– Supports up to two BPWM modules, each module provides one 16-bit counter and 6
output channels
– Supports independent mode for BPWM output/Capture input channel
– Supports 12-bit pre-scalar from 1 to 4096
– Supports 16-bit resolution BPWM counter
Up, down and up/down counter operation type
– Supports mask function and tri-state enable for each BPWM pin
– Supports interrupt on the following events:
