OMx/OLx — Output Mode/Output Level Bits
Channel 7 shares a pin with the pulse accumulator input pin. To use the PAI input, clear both the OM7
and OL7 bits and clear the OC7M7 bit in the output compare 7 mask register.
Freescale Semiconductor
These bit pairs select the output action to be taken as a result of a successful output compare. When
either OMx or OLx is set and the IOSx bit is set, the pin is an output regardless of the state of the
corresponding DDRT bit.
