CHAPTER 14 SERIAL ARRAY UNIT
(4) Serial communication operation setting register mn (SCRmn)
SCRmn is a communication operation setting register of channel n. It is used to set a data transmission/reception
mode, phase of data and clock, whether an error signal is to be masked or not, parity bit, start bit, stop bit, and data
length.
Rewriting SCRmn is prohibited when the register is in operation (when SEmn = 1).
SCRmn can be set by a 16-bit memory manipulation instruction.
Reset signal generation sets this register to 0087H.
