(37) Automatic receive switch compare register (AUTORCVCNT)
This register is used to set the time until the TRG_ON signal is set to the high level for the automatic receive
switch after the completion of transmit/receive when the mode is set to the automatic receive switch mode.
Initial value: 000AH = 10 symbols (Set value: 1H = 1 symbol)
The AUTORCVCNT register consists of 16 bits and can be accessed (serial interface communication) in 8
bit unit.
Reset signal generation sets this register to 000AH.
