R/W Description
R Reserved
These bits are always read as 0. The write value should
always be 0.
R/W Set the serial clock frequency for
transmission/reception.
The SCBRR setting can be determined from the following formula.
Pφ
Serial clock frequency =
2 (BRR + 1)
The units of Pφ (system clock frequency) and serial clock frequency are MHz.
25.3.3 Serial Control Register (SCSCR)
SCSCR is an 8-bit readable/writable register that selects transmit or receive operation, the serial
clock output, and whether to enable or disable interrupt requests for the smart card interface.
