Note: 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
, 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.
