UC4 to UC7
ISO UART RESET
START SESSION
LCT (Last Character to Transmit)
TRANSMIT/RECEIVE
not used
REG0 = 0, REG1 = 1, R/W = 0; UART TRANSMIT
UT0 to UT7
LSB to MSB of the character to be transmitted to the card
REG0 = 1, REG1 = 1, R/W = 0; PORTS EXTENSION (after reset all bits are cleared)
PE0 to PE5
PE6, PE7
PE0 to PE5 is the inverse of the value to be written on K0 to K5
not used
REG0 = 0, REG1 = 0, R/W = 1; UART RECEIVE
UR0 to UR7
LSB to MSB of the character received from the card
REG0 = 1, REG1 = 0, R/W = 1; UART STATUS REGISTER (after reset all bits are cleared)
US0
US1

US5 to US7
UART TRANSMIT buffer empty
UART RECEIVE buffer full
first start bit detected
parity error detected during reception of a character (the UART has asked the card to repeat the
character)
parity error detected during transmission of a character. The controller must write the previous
character in UART TRANSMIT, or abort the session.
