Bit Bit Name Initial Value R/W Description
2 MP 0 R/W Multiprocessor Mode (enabled only in
asynchronous mode)
When this bit is set to 1, the multiprocessor
communication function is enabled. The PE bit
and O/E bit settings are invalid in multiprocessor
mode.

Clock Select 1 and 0:
These bits select the clock source for the on-chip
baud rate generator.
00: φ clock (n = 0)
01: φ/4 clock (n = 1)
10: φ/16 clock (n = 2)
11: φ/64 clock (n = 3)
For the relation between the bit rate register
setting and the baud rate, see section 15.3.9, Bit
Rate Register (BRR). n is the decimal display of
the value of n in BRR (see section 15.3.9, Bit Rate
Register (BRR)).
Smart Card Interface Mode (When SMIF in SCMR is 1)
Bit Bit Name Initial Value R/W Description
7 GM 0 R/W GSM Mode
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, refer to section 15.7.8, Clock Output
Control.
6 BLK 0 R/W When this bit is set to 1, the SCI operates in block
transfer mode. For details on block transfer mode,
refer to section 15.7.3, Block Transfer Mode.
5 PE 0 R/W Parity Enable (enabled only in asynchronous
mode)
When this bit is set to 1, the parity bit is added to
transmit data before transmission, and the parity
bit is checked in reception. In Smart Card
interface mode, this bit must be set to 1.
