0
CKS0
0
R/W Clock Select 1 and 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 14.3.9, Bit Rate
Register (BRR). n is the decimal display of the value
of n in BRR (see section 14.3.9, Bit Rate Register
(BRR)).

Bit Bit Name Initial Value R/W Description
7
GM
0
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 14.7.8,
Clock Output Control.
6
BLK
0
R/W Setting this bit to 1 allows block transfer mode
operation. For details, see section 14.7.3, Block
Transfer Mode.
5
PE
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.
4
O/E
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 14.7.2, Data Format
(Except in Block Transfer Mode).
