Bit 5 = TB Timebase period selection bit
Bit 4 = TB1IE Timebase Interrupt enable bit
Bit 3 = TB1F Timebase Interrupt flag
Bits 2:0 = Reserved, must be kept cleared.
Lite Timer Input Capture register (LTICR)
Reset value: 0000 0000 (00h)
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.

This bit is set and cleared by software.
0: Timebase period = t
1: Timebase period = t
This bit is set and cleared by software.
0: Timebase (TB1) interrupt disabled
1: Timebase (TB1) interrupt enabled
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
