8.4.6 Timer Control 1 Register
The bits of the timer control 1 register (TCTL1) specify the action taken as a result of a successful OCx
compare.
OM2–OM5 — Output Mode Bits
OL2–OL5 — Output Level Bits
8.4.7 Timer Interrupt Mask 1 Register
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
Freescale Semiconductor
These control bit pairs are encoded to specify the action taken after a successful OCx compare. OC5
functions only if the I4/O5 bit in the PACTL register is clear. Refer to
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.

Bits in TMSK1 correspond bit for bit with flag bits in TFLG1. Ones in TMSK1
enable the corresponding interrupt sources.
