32-Bit Operation with Single Compare Mode
The previous examples all assume 16-bit single compare operations (T32 =
0
). Single Edge Compare modes can also operate with a 32-bit time
base, selected by setting T32 = 1
. Operation in 32-bit mode is
identical, except that the CCPxRB register is paired with CCPxRA to provide a 32-bit
compare value for CCPxTMR. CCPxRA is used for the upper 16 bits of the compare
value.
No period register is available to set the count period of CCPxTMR. If a count period less than FFFF FFFFh is desired, the module can be synchronized to an external source to set the count period.
