Legend:
R = Readable bit
-n = Value at POR
HC = Hardware Clearable
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 6-5
bit 4
bit 3
bit 2-0
Unimplemented: Read as ‘0’
ICSIDL: Input Capture x Module Stop in Idle Control bit
1 = Input capture module will halt in CPU Idle mode
0 = Input capture module will continue to operate in CPU Idle mode
Unimplemented: Read as ‘0’
ICTMR: Input Capture x Timer Select bit⁽¹⁾
1 = TMR2 contents are captured on capture event
0 = TMR3 contents are captured on capture event
ICI1:ICI0: Select Number of Captures per Interrupt bits
11 = Interrupt on every fourth capture event
10 = Interrupt on every third capture event
01 = Interrupt on every second capture event
00 = Interrupt on every capture event
ICOV: Input Capture x Overflow Status Flag bit (read-only)
1 = Input capture overflow occurred
0 = No input capture overflow occurred
ICBNE: Input Capture x Buffer Empty Status bit (read-only)
1 = Input capture buffer is not empty, at least one more capture value can be read
0 = Input capture buffer is empty
ICM2:ICM0: Input Capture x Mode Select bits
111 = Input capture functions as interrupt pin only when device is in Sleep or Idle mode (rising edge
detect only, all other control bits are not applicable)
110 = Unused (module disabled)
101 = Capture mode, every 16th rising edge
100 = Capture mode, every 4th rising edge
011 = Capture mode, every rising edge
010 = Capture mode, every falling edge
001 = Capture mode, every edge (rising and falling) – ICI<1:0> does not control interrupt generation
for this mode
000 = Input capture module turned off
Note 1: Timer selections may vary. Refer to the device data sheet for details.
