CH1 counter type
monitor
CH1 counter type
monitor
• 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
SD1886
CH1 selected
counter function
CH1 selected
counter function
• 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
SD1887 CH1 error code CH1 error code
This register stores the error code of an error occurred
in CH1.
SD1888
CH1 warning
code
CH1 warning code
This register stores the warning code of a warning
occurred in CH1.
SD1900
CH2 current value CH2 current value
• 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.
