bit 7 bit 0
Legend:
R = Readable bit HS = Set by Hardware ‘0’ = Bit is cleared
-n = Value at POR W = Writable bit U = Unimplemented bit, read as ‘0’
bit 15-9 Unimplemented: Read as ‘0’
bit 8 IC32: 32-Bit Timer Mode Select bit (Cascade mode)
1 = ODD IC and EVEN IC form a single 32-bit input capture module
(1)
0 = Cascade module operation is disabled
bit 7
ICTRIG: Trigger Operation Select bit
(2)
1 = Input source is used to trigger the input capture timer (Trigger mode)
0 = Input source is used to synchronize the input capture timer to a timer of another module
(Synchronization mode)
bit 6 TRIGSTAT: Timer Trigger Status bit
(3)
1 = ICxTMR has been triggered and is running
0 = ICxTMR has not been triggered and is being held clear
bit 5 Unimplemented: Read as ‘0’
Note 1: The IC32 bit in both the ODD and EVEN IC must be set to enable Cascade mode.
2: The input source is selected by the SYNCSEL<4:0> bits of the ICxCON2 register.
3: This bit is set by the selected input source (selected by the SYNCSEL<4:0> bits); it can be read, set and
cleared in software.
4: Do not use the ICx module as its own Sync or Trigger source.
5: This option should only be selected as a trigger source and not as a synchronization source.
