16-Bit Timer
9.6 16-Bit Timer Control Register
Advance Information
Address:
The 16-bit timer control register (TMRCR) is a read/write register
containing six control bits. Three bits control interrupts associated with
the timer status register flags ICF, OCF, and TOF.
ICIE — Input Capture Interrupt Enable Bit
OCIE — Output Compare Interrupt Enable Bit
TOIE — Timer Overflow Interrupt Enable Bit
TON — Timer On Bit
IEDG — Input Edge Bit
Reset:
Read:
Write:
When disabled, the timer is initialized to the reset condition.
Value of input edge determines which level transition on TCAP pin will
trigger free-running counter transfer to the input capture register.
Reset clears this bit.
