112/245
Bit 0 = TB2F Timebase 2 Interrupt flag
Lite timer autoreload register (LTARR)
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)
Reset value: 0000 0000 (00h)
Bits 7:0 = CNT[7:0] Counter 2 Reload value
Lite timer control/status register (LTCSR1)
Reset value: 0x00 0000 (x0h)
Bit 7 = ICIE Interrupt enable bit
CNT7
AR7
ICIE
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
This register is read by software. The LTARR value is automatically loaded into Counter
2 (LTCNTR) when an overflow occurs.
This bit is set and cleared by software.
0: Input Capture (IC) interrupt disabled
1: Input Capture (IC) interrupt enabled
