(9) Serial channel stop register 0 (ST0)
Symbol
ST0
The lower 8 bits of ST0 register can be set with an 1-bit or 8-bit memory manipulation instruction with ST0L.
Note Communication stops while holding the value of the control register and shift register, and the status of
Caution Be sure to clear bits 15 to 4 to “0”.
Remarks 1. n: Channel number (n = 0 to 3)
ST0 register is a trigger register that is used to enable stopping communication/count by each channel.
When 1 is written a bit of this register (ST0n), the corresponding bit (SE0n) of serial channel enable status
register 0 (SE0) is cleared to 0 (operation is stopped). Because ST0n bit is a trigger bit, it is cleared
immediately when SE0n = 0.
ST0 register can set written by a 16-bit memory manipulation instruction.
Reset signal generation clears ST0 register to 0000H.
