Lite timer autoreload register (LTARR)

Read / Write

Reset Value: 0000 0000 (00h)

●

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.

Lite timer counter 2 (LTCNTR)

Read only

Reset Value: 0000 0000 (00h)

●

Bits 7:0 =

CNT[7:0] Counter 2 Reload Value

This register is read by software. The LTARR value is automatically loaded into Counter

2 (LTCNTR) when an overflow occurs.

Lite timer control/status register (LTCSR1)

Read / Write

Reset Value: 0x00 0000 (x0h)

●

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

Note:

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.
