Note:
Bit 0 = TB2F Timebase 2 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 2 overflow
1: A Counter 2 overflow has occurred
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
After an MCU reset, software must initialise the ICF bit by reading the LTICR register
