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

bit 2-0
Unimplemented: Read as ‘0’
ICSIDL: Input Capture x Module Stop in Idle Control bit
1 = Input capture module halts in CPU Idle mode
0 = Input capture module continues to operate in CPU Idle mode
ICTSEL<2:0>: Input Capture Timer Select bits
111 = System clock (FOSC/2)
110 = Reserved
101 = Reserved
100 = Timer1
011 = Timer5
010 = Timer4
001 = Timer2
000 = Timer3
Unimplemented: Read as ‘0’
ICI<1:0>: 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
ICM<2:0>: Input Capture Mode Select bits⁽¹⁾
111 = Interrupt mode: 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 = Prescaler Capture mode: Capture on every 16th rising edge
100 = Prescaler Capture mode: Capture on every 4th rising edge
011 = Simple Capture mode: Capture on every rising edge
010 = Simple Capture mode: Capture on every falling edge
001 = Edge Detect Capture mode: Capture on every edge (rising and falling), ICI<1:0> bits do not
control interrupt generation for this mode
000 = Input capture module turned off
Note 1: The ICx input must also be configured to an available RPn pin. For more information, see Section 10.4
“Peripheral Pin Select”.
