POWER SUPPLY MANAGEMENT (PSM) INTERRUPT
The power supply monitor interrupt 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, Address 0xA9) enables the PSM interrupt (see Table 80).

The power management interrupt enable SFR (IPSME,
Address 0xEC) controls the events that result in a PSM
interrupt (see Table 21). Figure 33 illustrates 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 power management interrupt flag SFR,
Address 0xF8 (see Table 18).
