The Power Management Interrupt Enable SFR (IPSME, 0xEC)

controls the events that result in a PSM interrupt (see

POWER SUPPLY MONITOR INTERRUPT (PSM)

Table 20).

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

Figure 32 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

Table 70).
