• Manufacturer Part Number: MC9S12Q32VFA16
• Description: HCS12 Microcontrollers
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

To operate the 16-bit pulse accumulator independently of input capture or output compare 7 and 0
respectively the user must set the corresponding bits IOSx = 1, OMx = 0 and OLx = 0. OC7M7 in the
OC7M register must also be cleared. To enable output action using the OM7 and OL7 bits on the timer
port,the corresponding bit OC7M7 in the OC7M register must also be cleared. The settings for these bits
can be seen in
Note: in
IOSx is the register TIOS bit x,
OC7Mx is the register OC7M bit x,
TCx is timer Input Capture/Output Compare register,
IOCx is channel x,
OMx/OLx is the register TCTL1/TCTL2,
OC7Dx is the register OC7D bit x.

Output Mode — These control bits are encoded to specify the output action to be taken as a result of a
successful OCx compare. When either OMx or OLx is 1, the pin associated with OCx becomes an output tied to
OCx.
Note: To enable output action by OMx bits on timer port, the corresponding bit in OC7M should be cleared.
Output Level — These control bits are encoded to specify the output action to be taken as a result of a
successful OCx compare. When either OMx or OLx is 1, the pin associated with OCx becomes an output tied to
OCx.
Note: To enable output action by OLx bits on timer port, the corresponding bit in OC7M should be cleared.
