Chapter 22 Timer Module (TIM16B8CV2) Block Description
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.
IOCx = OC7Dx+ OMx/OLx, means that both OC7 event and OCx event will change channel x value.
