14.3.1
The main features of the smart-card interface are as follows.

Figure 14.2 shows a pin connection diagram for the smart card interface.
In communication with a smart card, data is transmitted and received over the same signal line.

be pulled up to V
If the smart card uses the clock generated by the smart card interface, connect the SCK
to the card’s CLK input. If the card uses its own internal clock, this connection is unnecessary.
The reset signal should be output from one of the H8/3048 Group’s generic ports.
In addition to these pin connections, power and ground connections will normally also be
necessary.
One frame consists of eight data bits and a parity bit.
In transmitting, a guard time of at least two elementary time units (2 etu) is provided between
the end of the parity bit and the start of the next frame. (An elementary time unit is the time
required to transmit one bit.)
In receiving, if a parity error is detected, a low error signal is output for 1 etu, beginning 10.5
etu after the start bit.
In transmitting, if an error signal is received, after at least 2 etu, the same data is automatically
transmitted again.
Only asynchronous communication is supported. There is no synchronous communication
function.
