Manufacturer Part Number
upd78f0114m6gb-8es
Description
8-bit Single-chip Microcontrollers
Manufacturer
Renesas Electronics Corporation.
Datasheet
CHAPTER 21 LOW-VOLTAGE DETECTOR
(b) When used as interrupt
Check that “supply voltage (V
) > detection voltage (V
)” in the servicing routine of the LVI interrupt by using bit
DD
LVI
0 (LVIF) of the low-voltage detection register (LVIM). Clear bit 0 (LVIIF) of interrupt request flag register 0L (IF0L)
to 0 and enable interrupts (EI).
In a system where the supply voltage fluctuation period is long in the vicinity of the LVI detection voltage, wait for
the supply voltage fluctuation period, check that “supply voltage (V
) > detection voltage (V
)” using the LVIF
DD
LVI
flag, and then enable interrupts (EI).
