POWER SUPPLY MANAGEMENT (PSM) INTERRUPT
The power supply management (PSM) 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, 0xA9) enables the PSM interrupt (see Table 60).

The Power Management Interrupt Enable SFR (IPSME, 0xEC)
controls the events that result in a PSM interrupt (see Table 19).
Figure 28 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 (see Table 16).
