Base Clock Pulse
Selects the number of base clock cycles in combination with
the BCP2 bit in SCMR.
Setting values in BCP2 bit in SCMR and BCP[1:0] bits in SMR:

PE
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.

Notes: 1. n is the decimal notation of the value of n in BRR (see section 20.2.9, Bit Rate Register (BRR)).
2. S is the value of S in BRR (see section 20.2.9, Bit Rate Register (BRR)).
3. Writable only when TE in SCR = 0 and RE in SCR = 0 (both serial transmission and reception are disabled).
SMR is used to set the SCI's serial transfer format and select the baud rate generator clock source.
