LITE TIMER (Cont’d)
11.1.6 Register Description
LITE TIMER CONTROL/STATUS REGISTER
(LTCSR)
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.
0: Timebase period = t
1: Timebase period = t
Bit 4 = TBIE Timebase Interrupt enable
This bit is set and cleared by software.
0: Timebase (TB) interrupt disabled
1: Timebase (TB) interrupt enabled
Bit 3 = TBF Timebase Interrupt Flag
This bit is set by hardware and cleared by software
reading the LTCSR register. Writing to this bit has
no effect.

Bit 2 = WDGRF Force Reset/ Reset Status Flag
This bit is used in two ways: it is set by software to
force a watchdog reset. It is set by hardware when
a watchdog reset occurs and cleared by hardware
or by software. It is cleared by hardware only when
an LVD reset occurs. It can be cleared by software
after a read access to the LTCSR register.
0: No watchdog reset occurred.
1: Force a watchdog reset (write), or, a watchdog
Bit 1 = WDGE Watchdog Enable
This bit is set and cleared by software.
0: Watchdog disabled
1: Watchdog enabled
Bit 0 = WDGD Watchdog Reset Delay
This bit is set by software. It is cleared by hard-
ware at the end of each t
0: Watchdog reset not delayed
1: Watchdog reset delayed

(LTICR)
Read only
Reset Value: 0000 0000 (00h)
Bit 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.
