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 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 (F
OSC/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
