bit 7

bit 0

Legend:

HCS = Hardware Clearable/Settable 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 x 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 12-10

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

bit 9-7

Unimplemented:

Read as ‘0’

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 x Overflow Status Flag bit (read-only)

= Input capture overflow occurred

= No input capture overflow occurred

bit 3

ICBNE:

Input Capture x 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(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
