R/W :
SPMR is an 8-bit read/write register that switches the CFG input system.
It is initialized to H'5F by a reset or in stand-by mode.
Bit 7
CTLSTOP Bit (CTLSTOP) : Controls whether the CTL circuit is operated or stopped.
Bit 7
CTLSTOP
Description
0
CTL circuit operates
(Initial value)
1
CTL circuit stops operation
Bit 6
Reserved: Cannot be modified and is always read as 1.
Bit 5
CFG Input System Switching Bit (CFGCOMP) : Selects whether the CFG input signal
system is set to the zero cross type comparator system or digital signal input system.
Bit 5
CFGCOMP
Description
0
CFG signal input system is set to the zero cross type comparator system.
(Initial value)
1
CFG signal input system is set to the digital signal input system.
Bits 4 to 0
Reserved: Cannot be modified and are always read as 1.
