8.4.7 Timer Interrupt Mask 1 Register
MC68HC711D3 — Rev. 2
MOTOROLA
NOTE:
The timer interrupt mask 1 register (TMSK1) is an 8-bit register used to enable or
inhibit the timer input capture and output compare interrupts.
OC1I–OC4I — Output Compare x Interrupt Enable Bits
I4/O5I — Input Capture 4 or Output Compare 5 Interrupt Enable Bit
IC1I–IC3I — Input Capture x Interrupt Enable Bits
Bits in TMSK1 correspond bit for bit with flag bits in TFLG1. Ones in TMSK1 enable
the corresponding interrupt sources.
Address:
If the OCxI enable bit is set when the OCxF flag bit is set, a hardware interrupt
sequence is requested.
When I4/O5 in PACTL is one, I4/O5I is the input capture 4 interrupt enable bit.
When I4/O5 in PACTL is 0, I4/O5I is the output compare 5 interrupt enable bit.
If the ICxI enable bit is set when the ICxF flag bit is set, a hardware interrupt
sequence is requested.
