12.5 Registers and Reset Initialization
This section describes the registers and reset initialization.
12.5.1 Timer IC/OC Select Register
Read: Anytime
Write: Anytime
IOS7–IOS0 — Input Capture or Output Compare Select Bits
12.5.2 Timer Compare Force Register
Read: Anytime; always read $00 (1 state is transient)
Write: Anytime
FOC7–FOC0 — Force Output Compare Bits
Freescale Semiconductor
The IOSx bits enable input capture or output compare operation for the corresponding timer channel.
Setting an FOCx bit causes an immediate output compare on the corresponding channel. Forcing an
output compare does not set the output compare flag.
1 = Output compare enabled
0 = Input capture enabled
1 = Force output compare
0 = No effect
