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 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

bit 12-10

ICTSEL<2:0>: Input Capture x 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

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

bit 4

ICOV: Input Capture x Overflow Status Flag bit (read-only)

1 = Input capture overflow occurred

0 = No input capture overflow occurred

bit 3

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

bit 2-0

ICM<2:0>: Input Capture Mode Select bits

111 = Interrupt mode: Input capture 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 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 is turned off
