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 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).
Enable external interrupt 1. This bit controls the masking of external interrupt 1.
0 = Disable external interrupt 1.
1 = Enable all interrupt requests generated by the INT1 pin.
Enable timer 0 interrupt. This bit controls the masking of the timer 0 interrupt.
0 = Disable all timer 0 interrupts.
1 = Enable all interrupt requests generated by the TF0 flag (TCON.5).
Enable external interrupt 0. This bit controls the masking of external interrupt 0.
0 = Disable external interrupt 0.
1 = Enable all interrupt requests generated by the INT0 pin.
