● Bits 7:0 = AR[7:0] Counter 2 Reload Value
These bits register is read/write by software. The LTARR value is automatically loaded
into Counter 2 (LTCNTR) when an overflow occurs.

Note:
● Bit 7 = ICIE Interrupt Enable
This bit is set and cleared by software.
0: Input Capture (IC) interrupt disabled
1: Input Capture (IC) interrupt enabled
● 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
After an MCU reset, software must initialise the ICF bit by reading the LTICR register
● Bit 5 = TB Timebase period selection
This bit is set and cleared by software.
