20.8.1
A channel flag is set when an input capture or output compare event occurs. Clear a channel flag by writing
a 1 to it.
Freescale Semiconductor
When DDR set the pin as input (0), reading the data register will return the state of the pin. When DDR set the pin as output (1),
reading the data register will return the content of the data latch. Pin conditions such as rising or falling edges can trigger an input
capture on a pin configured as an input.
OMn/OLn bit pairs select the output action to be taken as a result of a successful output compare. When either OMn or OLn is
set and the IOSn bit is set, the pin is an output regardless of the state of the corresponding DDR bit.
Setting an OC3M bit configures the corresponding PORTTn pin to be output. OC3Mn makes the PORTTn pin an output regardless
of the data direction bit when the pin is configured for output compare (IOSn = 1). The OC3Mn bits do not change the state of the
PORTTnDDR bits.
X = Don’t care
An output compare overrides the data direction bit of the output compare pin but does not change the state of the data direction
bit. Enabling output compare disables data register drive of the pin.
A successful output compare on channel 3 causes an output value determined by OC3Dn value to temporarily override the output
compare pin state of any other output compare channel.The next OC action for the specific channel will still be output to the pin.
A channel 3 output compare can cause bits in the output compare 3 data register to transfer to the GPT port data register,
depending on the output compare 3 mask register.
