Preliminary Technical Data
POWER SUPPLY MONITOR INTERRUPT (PSM)
The power supply monitor interrupt (PSM) alerts the 8052 core
of power supply events. The PSM interrupt is disabled by
default. Setting the EPSM bit in the Interrupt Enable and
Priority 2 SFR (IEIP2, 0xA9) enables the PSM interrupt.

The Power Management Interrupt Enable SFR (IPSME, 0xEC)
controls the events that result in a PSM interrupt. Figure 23 is a
diagram illustrating how the PSM interrupt vector is shared
among the PSM interrupt sources. The PSM interrupt flags are
latched and must be cleared by writing to the flag register.
