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

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.
