Global Interrupt Enable. This bit controls the global masking of all interrupts
except Power-Fail Interrupt, which is enabled by the EPFI bit (WDCON.5).
0 = Disable all interrupt sources. This bit overrides individual interrupt mask
settings.
1 = Enable all individual interrupt masks. Individual interrupts will occur if
enabled.
Enable Serial Port 1 Interrupt. This bit controls the masking of the serial port
1 interrupt.
0 = Disable all serial port 1 interrupts.
1 = Enable interrupt requests generated by the RI_1 (SCON1.0) or TI_1
(SCON1.1) flags.
Enable Timer 2 Interrupt. This bit controls the masking of the Timer 2
interrupt.
0 = Disable all Timer 2 interrupts.
1 = Enable interrupt requests generated by the TF2 flag (T2CON.7).
Enable Serial Port 0 Interrupt. This bit controls the masking of the serial port
0 interrupt.
0 = Disable all serial port 0 interrupts.
1 = Enable interrupt requests generated by the RI_0 (SCON0.0) or TI_0
(SCON0.1) flags.
Enable Timer 1 Interrupt. This bit controls the masking of the Timer 1
interrupt.
0 = Disable all Timer 1 interrupts.
1 = Enable all interrupt requests generated by the TF1 flag (TCON.7).
