Explanation
This register stores a value indicating the counter type for
high-speed counter of CH1 set by the parameter.
Counter selection is disabled (fixed at "0") when a value
stored to CH1 operation mode monitor (SD1884) is other
than "1" (normal mode).
• 0: Linear counter
• 1: Ring counter
This register stores a value indicating the selected counter
function for high-speed counter of CH1 set by the parameter.
Counter selection is disabled (fixed at "0") when a value
stored to CH1 operation mode monitor (SD1884) is other
than "1" (normal mode).
• 0: Count disabling function
• 1: Latch counter function
• 2: Sampling counter function
• 3: Count disabling/preset function
• 4: Latch counter/preset function
This register stores the error code of an error occurred in
CH1.
This register stores the warning code of a warning occurred
in CH1.
• This register stores the current counter value of CH2 at
END processing.
• When the ICCNTRD2 instruction is executed, this register
is updated by the current value at that moment.
The current value is updated at END processing and by the
ICCNTRD2 instruction only when Normal Mode is set for
Operation Mode Setting (high-speed counter function
parameter). The range of a value that can be read is from -
2147483648 to 2147483647.
This register stores each status of CH2.
