30.4 Operation
30.4.1 Overview
The main functions of the smart card interface are as follows.
• One frame consists of 8-bit data and one parity bit.
• During transmission, a character protection time, set using SCGRD and the LCB and PB bits
in SCSCMR, is inserted between the end of each parity bit and the beginning of the next
frame.
• During reception in T = 0 mode, when a parity error is detected, low level is output for a
duration of 1 etu as an error signal, 10.5 etus after the start bit.
• During transmission in T = 0 mode, if an error signal is sampled, after 2 etus or more have
elapsed, the same data is automatically transmitted.
• Only asynchronous communication functions are supported; there is no clocked synchronous
communication function.
