Timer Interface A (TIMA)
11.10.1 TIMA Status and Control Register
Technical Data
214
Address
The TIMA status and control register:
Reset:
TOF — TIMA Overflow Flag Bit
TOIE — TIMA Overflow Interrupt Enable Bit
Read:
Write:
•
•
•
•
•
This read/write flag is set when the TIMA counter reaches the modulo
value programmed in the TIMA counter modulo registers. Clear TOF
by reading the TIMA status and control register when TOF is set and
then writing a logic 0 to TOF. If another TIMA overflow occurs before
the clearing sequence is complete, then writing logic 0 to TOF has no
effect. Therefore, a TOF interrupt request cannot be lost due to
inadvertent clearing of TOF. Reset clears the TOF bit. Writing a logic
1 to TOF has no effect.
This read/write bit enables TIMA overflow interrupts when the TOF bit
becomes set. Reset clears the TOIE bit.
:
1 = TIMA counter has reached modulo value.
0 = TIMA counter has not reached modulo value.
1 = TIMA overflow interrupts enabled
0 = TIMA overflow interrupts disabled
