LITE TIMER (Cont’d)
Bit 6 = ICF Input Capture Flag
This bit is set by hardware and cleared by software
by reading the LTICR register. Writing to this bit
does not change the bit value.
0: No input capture
1: An input capture has occurred
Note: After an MCU reset, software must initialize
the ICF bit by reading the LTICR register
Bit 5 = TB Timebase period selection
This bit is set and cleared by software.
0: Timebase period = t
* 8000 (1ms @ 8 MHz)
OSC
1: Timebase period = t
* 16000 (2ms @ 8
OSC
MHz)
Bit 4 = TB1IE Timebase Interrupt enable
This bit is set and cleared by software.
0: Timebase (TB1) interrupt disabled
1: Timebase (TB1) interrupt enabled
Bit 3 = TB1F Timebase Interrupt Flag
This bit is set by hardware and cleared by software
reading the LTCSR register. Writing to this bit has
no effect.
0: No counter overflow
1: A counter overflow has occurred
Bits 2:0 = Reserved

Bits 7:0 = ICR[7:0] Input Capture Value
These bits are read by software and cleared by
hardware after a reset. If the ICF bit in the LTCSR
is cleared, the value of the 8-bit up-counter will be
captured when a rising or falling edge occurs on
the LTIC pin.
