LITE TIMER (Cont’d)
11.3.4 Low Power Modes
11.3.5 Interrupts
Note: The TBxF and ICF interrupt events are con-
nected to separate interrupt vectors (see Inter-
rupts chapter).
They generate an interrupt if the enable bit is set in
the LTCSR1 or LTCSR2 register and the interrupt
mask in the CC register is reset (RIM instruction).
11.3.6 Register Description
LITE TIMER CONTROL/STATUS REGISTER 2
(LTCSR2)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 7:2 = Reserved, must be kept cleared.
Bit 1 = TB2IE Timebase 2 Interrupt enable
This bit is set and cleared by software.
0: Timebase (TB2) interrupt disabled
1: Timebase (TB2) interrupt enabled
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
(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 val-
ue is automatically loaded into Counter 2 (LTCN-
TR) when an overflow occurs.
