Operands:
D: Device for storing the measuring time (unit: 1us)
(time unit: 1us)
Explanations:
1. Range of D: K0 ~ K9
2. Range of n: K10 ~ K500
3. The designated special D registers (D1156 ~ D1165) can measure up to 10 interruption subroutines. For
example, when D = K5, the designated D register will be D1161.
4. When RTMU is executed, if the D and n entered by the user are legal, interruption of the timer will be enabled
and the counting starts and the special D designated by D is cleared as 0. When RTMD is executed,
interruption of the timer is disabled and the calculated time will be assigned to special D designated by RTMD.
5. With API 153 RTMD, RTMU can measure the execution time of "I" interruption service subroutine, which can
be reference for dealing with the high-speed response when the user is at the initial stage of developing the
program.

D
Operands:
D: Device to store the measuring time (unit: 1us).
Explanations:
1. Range of D: K0 ~ K9. The No. of D has to be the same as that designated by D in API 152 RTMU; otherwise the
result of the measurement may be unexpectable.
Program Example:
When X0 goes from Off to On, the program will enter I001 interruption subroutine. RTMU will activate an 8-bit timer
(unit: 10us) and RTMD (when D = K0) will shut down the timer and store the time in the timer in special D registers
(D1156 ~ D1165, designated by K0 ~ K9).
