Interrupt Priority SFR (IP, 0xB8) Bit No. Address Mnemonic Description 7 0xBF PADE ADE Energy Measurement Interrupt Priority (1 = high, 0 = low). 6 0xBE PTEMP Temperature ADC Interrupt Priority (1 = high, 0 = low). 5 0xBD PT2 Timer 2 Interrupt Priority (1 = high, 0 = low). 4 0xBC PS UART Serial Port Interrupt Priority (1 = high, 0 = low). 3 0xBB PT1 Timer 1 Interrupt Priority (1 = high, 0 = low). 2 0xBA PX1 INT1 (External Interrupt 1) Priority (1 = high, 0 = low). 1 0xB9 PT0 Timer 0 Interrupt Priority (1 = high, 0 = low). 0 0xB8 PX0 INT0 (External Interrupt 0) Priority (1 = high, 0 = low). Table 66. Interrupt Enable and Priority 2 SFR (IEIP2, 0xA9) Bit No. Mnemonic Description 7 – – 6 PTI RTC Interrupt Priority (1 = high, 0 = low). 5 – – 4 PSI SPI/I2C Interrupt Priority (1 = high, 0 = low). 3 EADE Enables the Energy Metering Interrupt (ADE). Set by the user. 2 ETI Enables the RTC Interval Timer Interrupt. Set by the user. 1 EPSM Enables the PSM Power Supply Management Interrupt. Set by the user. 0 ESI Enables the SPI/I2C Interrupt. Set by the user. INTERRUPT PRIORITY If two interrupts of the same priority level occur simultaneously, the polling sequence is observed (as shown in Table 67). Table 67.
