Description
0
R/W
Clock Select 1 and 0
0
R/W
These bits select the clock source for the 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 13.3.9, Bit Rate Register
(BRR). n is the decimal display of the value of n in BRR
(see section 13.3.9, Bit Rate Register (BRR)).

R/W
GSM Mode
Setting this bit to 1 allows GSM mode operation. In GSM
mode, the TEND set timing is put forward to 11.0 etu*
from the start and the clock output control function is
appended. For details, see section 13.7.8, Clock Output
Control.
0
R/W
Setting this bit to 1 allows block transfer mode operation.
For details, see section 13.7.3, Block Transfer Mode.
0
R/W
Parity Enable (valid 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. Set this bit to 1 in smart card interface mode.
0
R/W
Parity Mode (valid only when the PE bit is 1 in
asynchronous mode)
0: Selects even parity
1: Selects odd parity
For details on the usage of this bit in smart card interface
mode, see section 13.7.2, Data Format (Except in Block
Transfer Mode).
