Legend:

HC = Hardware Clearable bit

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15-14

Unimplemented:

Read as ‘0’

bit 13

ICSIDL:

Input Capture Module Stop in Idle Control bit

= Input capture module halts in CPU Idle mode

= Input capture module continues to operate in CPU Idle mode

bit 12-8

Unimplemented:

Read as ‘0’

bit 7

ICTMR:

Input Capture Timer Select bits

= TMR2 contents are captured on capture event

= TMR3 contents are captured on capture event

bit 6-5

ICI<1:0>:

Select Number of Captures per Interrupt bits

= Interrupt on every fourth capture event

= Interrupt on every third capture event

= Interrupt on every second capture event

= Interrupt on every capture event

bit 4

ICOV:

Input Capture Overflow Status Flag bit (read-only)

= Input capture overflow occurred

= No input capture overflow occurred

bit 3

ICBNE:

Input Capture Buffer Empty Status bit (read-only)

= Input capture buffer is not empty, at least one more capture value can be read

= Input capture buffer is empty

bit 2-0

ICM<2:0>:

Input Capture 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> bits do not control interrupt generation

for this mode.

000

= Input capture module turned off
