This mode is used to transfer data between specific microcomputers among multiple microcomputers
connected using UARTi. The sleep mode is selected when the sleep select bit (bit 7 at addresses
03A0
the MSB of the received data = “1” and does not perform receive operation when the MSB = “0”.
When the data logic select bit (bit 6 of address 037D

ample of timing for switching serial data logic.
