which is prescribed by the smart card standard, and corresponds to state Z. Since the SINV bit of
this LSI only inverts data bits D7 to D0, write 1 to the O/E bit in SMR to invert the parity bit in
both transmission and reception.
14.7.3
Block transfer mode is different from normal smart card interface mode in the following respects.
• If a parity error is detected during reception, no error signal is output. Since the PER bit in SSR
• During transmission, at least 1 etu is secured as a guard time after the end of the parity bit
• Since the same data is not re-transmitted during transmission, the TEND flag in SSR is set 11.5
• Although the ERS flag in block transfer mode displays the error signal status as in normal
14.7.4
Only the internal clock generated by the internal baud rate generator can be used as a
communication clock in smart card interface mode. In this mode, the SCI can operate using a basic
clock with a frequency of 32, 64, 372, or 256 times the bit rate according to the BCP1 and BCP0
settings (the frequency is always 16 times the bit rate in normal asynchronous mode). At
reception, the falling edge of the start bit is sampled using the internal basic clock in order to
perform internal synchronization. Receive data is sampled at the 16th, 32nd, 186th and 128th
rising edges of the basic clock pulses so that it can be latched at the center of each bit as shown in
figure 14.28. The reception margin here is determined by the following formula.
Assuming values of F = 0, D = 0.5, and N = 372 in formula (1), the reception margin is
determined by the formula below.
