ES: Serial Port interrupt enable bit.
ET1: Timer 1 interrupt enable bit.
EX1: External interrupt 1 enable bit.
ET0: Timer 0 interrupt enable bit.
EX0: External interrupt 0 enable bit.
AUXIE (Address=ADH, Interrupt Enable Register 2)
EUSB: USB interrupt enable bit.
ETWSI: 2-wire-Serial-Interface interrupt enable bit.
EKBI: Keypad interrupt enable bit.
ESPI: SPI interrupt enable bit.
XICON (Address=C0H, External Interrupt Control Register)
IL3: External interrupt 3 level control bit.
1: rising-edge/high-level activated.
0: falling-edge/low-level activated.
EX3: External interrupt 3 enable bit.
IE3: External interrupt 3 interrupt flag.
IT3: External interrupt 3 type control bit.
1: edge-triggered.
0: level-triggered.
IL2: External interrupt 2 level control bit.
1: rising-edge/high-level activated.
0: falling-edge/low-level activated.
EX2: External interrupt 2 enable bit.
