Chapter 22 Timer Module (TIM16B8CV2) Block Description
MC9S12XE-Family Reference Manual Rev. 1.25
800 Freescale Semiconductor
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 Table 22-10
Table 22-10. The OC7 and OCx event priority
Note: in Table 22-10, the IOS7 and IOSx should be set to 1
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.
IOCx = OC7Dx+ OMx/OLx, means that both OC7 event and OCx event will change channel x value.
