Description
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 16.7.2, Data Format
(Except in Block Transfer Mode).
Basic Clock Pulse 1,0
These bits select the number of basic clock cycles in
a 1-bit data transfer time in smart card interface
mode.
00: 32 clock cycles (S = 32)
01: 64 clock cycles (S = 64)
10: 372 clock cycles (S = 372)
11: 256 clock cycles (S = 256)
For details, see section 16.7.4, Receive Data
Sampling Timing and Reception Margin. S is
described in section 16.3.9, Bit Rate Register (BRR).
Clock Select 1,0
These bits select the clock source for the baud rate
generator.
00: clock (n = 0)
01: /4 clock (n = 1)
10: /16 clock (n = 2)
11: /64 clock (n = 3)
For the relation between the bit rate register setting
and the baud rate, see section 16.3.9, Bit Rate
Register (BRR). n is the decimal display of the value
of n in BRR (see section 16.3.9, Bit Rate Register
(BRR)).
