PWM AUTO-RELOAD TIMER (Cont’d)
INPUT CAPTURE
CONTROL / STATUS REGISTER (ICCSR)
Read /Write
Reset Value: 0000 0000 (00h)
Bit 7:6 = Reserved, always read as 0.
Bit 5:4 = CS[2:1] Capture Sensitivity
These bits are set and cleared by software. They
determine the trigger event polarity on the corre-
sponding input capture channel.
0: Falling edge triggers capture on channel x.
1: Rising edge triggers capture on channel x.
Bit 3:2 = CIE[2:1] Capture Interrupt Enable
These bits are set and cleared by software. They
allow to enable or not the Input capture channel in-
terrupts independently.
0: Input capture channel x interrupt disabled.
1: Input capture channel x interrupt enabled.
Bit 1:0 = CF[2:1] Capture Flag
These bits are set by hardware and cleared by
software reading the corresponding ICRx register.
Each CFx bit indicates that an input capture x has
occurred.
0: No input capture on channel x.
1: An input capture has occured on channel x.
INPUT CAPTURE REGISTERS (ICRx)
Read only
Reset Value: 0000 0000 (00h)
Bit 7:0 = IC[7:0] Input Capture Data
These read only bits are set and cleared by hard-
ware. An ICRx register contains the 8-bit auto-re-
load counter value transferred by the input capture
channel x event.
