13.8.3 Output Compare Functions
13-14
MOTOROLA
An input capture occurs every time a selected edge is detected, even when the input
capture status flag is set. This means that the value read from the input capture regis-
ter corresponds to the most recent edge detected, which may not be the edge that
caused the status flag to be set.
Each GPT output compare pin has an associated 16-bit compare register and a 16-bit
comparator. Each output compare function has an associated status flag, and can
cause the GPT to make an interrupt service request. Output compare logic is designed
to prevent false compares during data transition times.
When the programmed content of an output compare register matches the value in
TCNT, an output compare status flag (OCxF) bit in TFLG1 is set. If the appropriate in-
terrupt enable bit (OCxI) in TMSK1 is set, an interrupt request is made when a match
occurs. Refer to <Bold>11.4.2 GPT Interrupts for more information.
Operation of output compare 1 differs from that of the other output compare functions.
OC1 control logic can be programmed to make state changes on other OC pins when
an OC1 match occurs. Control bits in the timer compare force register (CFORC) allow
for early forced compares.
