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 (see Table 68).

The Power Management Interrupt Enable SFR (IPSME, 0xEC)
controls the events that result in a PSM interrupt (see Table 20).
Figure 31 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 IPSMF flag
register.
