Interrupts

Note:

The TBxF and ICF interrupt events are connected to separate interrupt vectors (see

Interrupts 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

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.
