bit 7

bit 0

Legend:

HSC = Hardware Settable/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 x Stop in Idle Control bit

= Input Capture x halts in CPU Idle mode

= Input Capture x continues to operate in CPU Idle mode

bit 12-10

ICTSEL<2:0>:

Input Capture x Timer Select bits

111

= System clock (FOSC/2)

110

= Reserved

101

= Reserved

100

= Timer1

011

= Reserved

010

= Reserved

001

= Timer2

000

= Timer3

bit 9-7

Unimplemented:

Read as ‘0’

bit 6-5

ICI<1:0>:

Input Capture x 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 x overflow has occurred

= No Input Capture x overflow has occurred

bit 3

ICBNE:

Input Capture x Buffer Empty Status bit (read-only)

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

= Input Capture x buffer is empty

bit 2-0

ICM<2:0>:

Input Capture x Mode Select bits(1)

111

= Interrupt mode: Input Capture x functions as an interrupt pin only when the device is in Sleep or

Idle mode (rising edge detect only, all other control bits are not applicable)

110

= Unused (module is 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 x module is turned off

Note 1:

The ICx input must also be configured to an available RPn/RPIn pin. For more information, see

Section 11.5 “Peripheral Pin Select (PPS)”
