(7) Serial flag clear trigger register mn (SIRmn)
Symbol
SIRmn
SIRmn is a trigger register that is used to clear each error flag of channel n.
When each bit (FECTmn, PECTmn, OVCTmn) of this register is set to 1, the corresponding bit (FEFmn,
PEFmn, OVFmn) of serial status register mn is cleared to 0. Because SIRmn is a trigger register, it is cleared
immediately when the corresponding bit of SSRmn is cleared.
SIRmn can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of SIRmn can be set with an 8-bit memory manipulation instruction with SIRmnL.
Reset signal generation clears this register to 0000H.
Caution Be sure to clear bits 15 to 3 to “0”.
