Note:
Voltage Detection and Flags
The Voltage Detection register (LVD, register 0Ch at the expanded register bank 0Dh)
offers an option of monitoring the V
0 of LVD register is set. Once Voltage Detection is enabled, the V
real time. The HVD Flag (bit 2 of the LVD register) is set only if V
V
When Voltage Detection is enabled, the LVD Flag also triggers IRQ5. The IRQ bit 5
latches the low-voltage condition until it is cleared by instructions or reset. The IRQ5
interrupt is served if it is enabled in the IMR register. Otherwise, bit 5 of IRQ register is
latched as a Flag only.
If it is necessary to receive an LVD interrupt upon power-up at an operating voltage lower
than the low battery detect threshold, enable interrupts using the Enable Interrupt (EI)
instruction prior to enabling the voltage detection.
