Interrupt priority SFR (IP, 0xB8) Bit Location Bit Addr. Bit Name 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 64. Interrupt Enable and Priority 2 SFR (IEIP2, 0xA9) Bit Location Bit 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 Set by the user to enable the Energy Metering Interrupt (ADE) 2 ETI Set by the user to enable the RTC Interval Timer interrupt. 1 EPSM Set by the user to enable the PSM Power Supply Management interrupt. 0 ESI Set by the user to enable the SPI/I2C interrupt. Table 65. WatchDog Timer SFR (WDCON, 0xC0) Bit Location Bit Addr. Bit Name Default Value Description 7-4 0xC7 – 0xC4 PRE[3:0] 7 Watchdog pre-scaler. In normal mode, the 16-bit watchdog timer is clocked by the input clock (32.768kHz). The PRE bits set which of the upper bits of the counter are used as the watchdog output following: CLKIN t PRE watchdog 9 2 2 × = [3:0] Watchdog Timeout 0000 15.6ms 0001 31.2ms 0010 62.5ms 0011 125ms 0100 250ms 0101 500ms 0110 1s 0111 2s 1000 0 Automatic Reset 1001 0 Serial download reset 1010 to 1111 Not a valid selection 3 0xC3 WDIR 0 Watchdog interrupt response bit. When clear, watchdog will generate a system reset when the watchdog time out period has expired When set, the watchdog will generate a interrupt when the watchdog time out period has expired. |
