Explanation
This register stores each status of CH1.

• 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.
