Interrupts
Table 40.
The TBxF and ICF interrupt events are connected to separate interrupt vectors (see
Section 7:
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).
Register description
Lite Timer Control/Status register 2 (LTCSR2)
Reset value: 0000 0000 (00h)
Bits 7:2 = Reserved, must be kept cleared.
Bit 1 = TB2IE Timebase 2 Interrupt enable bit
Bit 0 = TB2F Timebase 2 Interrupt flag
Timebase 1 Event
Timebase 2 Event
Interrupt Event
This bit is set and cleared by software.
0: Timebase (TB2) interrupt disabled
1: Timebase (TB2) interrupt enabled
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
