CH1 external I/O
status monitor
• This register stores a value indicating the external I/
O signal status of CH1.
• Unused signal status is fixed at off.
• When Normal Mode is set for Operation Mode
Setting (high-speed counter function parameter), a
value according to the setting configured for
Function Input Logic Setting (high-speed counter
function parameter) is stored in the function input
status. Therefore, when a voltage is applied to the
function input terminal while Negative logic is set for
Function input logic setting, this register turns off.
• When other than A Phase/B Phase is selected for
Count Source Selection (high-speed counter function
parameter), the phase A input status and phase B
input status are fixed at off.
