Operands:
D
: The address offset for the execution time of an I interrupt (unit: 1us)
n
: time base. Parameter
range: K10 ~ K500 (units: 1us)
Description:
1. Range
of
D
: K0 ~ K9
2. Range
of
n
: K10 ~ K500
3.
The special D registers (D1156 ~ D1165) are used to measure the execution time of up to 10
interrupt subroutines. For example, when
D
= K5, the D register will be D1161.
4.
When RTMU is executed, if the
D
and
n
entered by the user are legal, the timer will be
enabled and the special D register designated by
D
is cleared to 0. When RTMD is executed,
the instruction will measure the execution time of the interrupt and store the result in the
special D register specified by
D.
