LITE TIMER (Cont’d)
Input Capture
The 8-bit input capture register is used to latch the
free-running upcounter after a rising or falling edge
is detected on the LTIC pin. When an input capture
occurs, the ICF bit is set and the LTICR register
contains the MSB of the free-running upcounter.
An interrupt is generated if the ICIE bit is set. The
ICF bit is cleared by reading the LTICR register.
The LTICR is a read only register and always con-
tains the data from the last input capture. Input
capture is inhibited if the ICF bit is set.
10.1.4 Low Power Modes
10.1.5 Interrupts
Note: The TBF and ICF interrupt events are con-
nected to separate interrupt vectors (see Inter-
rupts chapter).
They generate an interrupt if the enable bit is set in
the LTCSR register and the interrupt mask in the
CC register is reset (RIM instruction).
