Description
When this bit is set to 1, the SCI operates in GSM
mode. In GSM mode, the timing of the TEND setting is
advanced by 11.0 etu (Elementary Time Unit: the time
for transfer of one bit), and clock output control mode
addition is performed. For details, see section 13.7.8,
Clock Output Control.
When this bit is set to 1, the SCI operates in block
transfer mode. For details on block transfer mode, see
section 13.7.3, Block Transfer Mode.
When this bit is set to 1, the parity bit is added to
transmit data in transmission, and the parity bit is
checked in reception. In smart card interface mode, this
bit must be set to 1.
asynchronous mode)
0: Selects even parity.
1: Selects odd parity.
For details on setting this bit in smart card interface
mode, see section 13.7.2, Data Format (Except for
Block Transfer Mode).
Basic Clock Pulse 1 and 2
These bits specify the number of basic clock periods in
a 1-bit transfer interval on the smart card interface.
00: 32 clock (S = 32)
01: 64 clock (S = 64)
10: 372 clock (S = 372)
11: 256 clock (S = 256)
For details, see section 13.7.4, Receive Data Sampling
Timing and Reception Margin in smart card Interface
Mode. S stands for the value of S in BRR (see section
13.3.9, Bit Rate Register (BRR)).
