(9) Serial channel start register m (SSm)
Symbol
Symbol
SS0
SS1
SSm is a trigger register that is used to enable starting communication/count by each channel.
When 1 is written a bit of this register (SSmn), the corresponding bit (SEmn) of serial channel enable status
register m (SEm) is set to 1. Because SSmn is a trigger bit, it is cleared immediately when SEmn = 1.
SSm can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of SSm can be set with an 1-bit or 8-bit memory manipulation instruction with SSmL.
Reset signal generation clears this register to 0000H.
Caution Be sure to clear bits 15 to 4 of SS0, and bits 15 to 4, 1 and 0 of SS1 to “0”.
Remarks 1. m: Unit number (m = 0, 1), n: Channel number (n = 0 to 3), mn = 00 to 03, 12, 13

2. When the SSm register is read, 0000H is always read.
No trigger operation
Sets SEmn to 1 and enters the communication wait status (if a communication operation is already under
execution, the operation is stopped and the start condition is awaited).
