INDUCTION MOTOR CONTROLLER (Cont’d)
7.4.5.2 IMC Software Operating mode
In this operating mode, the Repetition register and
any Compare register can be independently up-
dated by software by setting the SDT bit in the
PCR2 register (this bit will be reset by hardware)
and the corresponding enable bit in the same reg-
ister.
No hardware loading is performed when an ADT
interrupt is generated.
Note: The Repetition Counter is decremented im-
mediately when the Repetition Counter is updated.
