Description
Base clock Pulse 1, 0
These bits select the number of base 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 19.7.4, Receive Data Sampling
Timing and Reception Margin. S is described in section
19.3.9, Bit Rate Register (BRR).
Clock Select 1, 0
These bits select the clock source for the baud rate
generator.
00: Pφ clock (n = 0)
01: Pφ/4 clock (n = 1)
10: Pφ/16 clock (n = 2)
11: Pφ/64 clock (n = 3)
For the relation between the settings of these bits and the
baud rate, see section 19.3.9, Bit Rate Register (BRR). n
is the decimal display of the value of n in BRR (see
section 19.3.9, Bit Rate Register (BRR)).
