Serial mode register 2A (SM2A: $01B) is a 4-bit write-only register. It is reset to $0 by MCU reset.
A write signal input to serial mode register 2A (SM2A: $01B) discontinues the input of the transmit clock
to serial data register 2 (SR2L: $01D, SR1U: $01E) and the octal counter, and the octal counter is reset to
