MOTOROLA
LVISTOP, LVIPWRD, LVI5OR3, and LVIRSTD are in the configuration
register (MOR1). See
LVI’s configuration bits. Once an LVI reset occurs, the MCU remains in
reset until V
exit reset. See
interaction between the SIM and the LVI. The output of the comparator
controls the state of the LVIOUT flag in the LVI status register (LVISR).
An LVI reset also drives the RST pin low to provide low-voltage
protection to external peripheral devices.
