Global Interrupt Enable. This bit controls the global masking of all interrupts except those in AIE (SFR A6h).

bit 7

0: Disable interrupt sources. This bit overrides individual interrupt mask settings for this register.

1: Enable all individual interrupt masks. Individual interrupts in this register will occur if enabled.

ES1

Enable Serial Port 1 Interrupt. This bit controls the masking of the serial Port 1 interrupt.

bit 6

0: Disable all serial Port 1 interrupts.

1: Enable interrupt requests generated by the RI_1 (SCON1.0, SFR C0h) or TI_1 (SCON1.1, SFR C0h) flags.

ET2

Enable Timer 2 Interrupt. This bit controls the masking of the Timer 2 interrupt.

bit 5

0: Disable all Timer 2 interrupts.

1: Enable interrupt requests generated by the TF2 flag (T2CON.7, SFR C8h).

ES0

Enable Serial port 0 interrupt. This bit controls the masking of the serial Port 0 interrupt.

bit 4

0: Disable all serial Port 0 interrupts.

1: Enable interrupt requests generated by the RI_0 (SCON0.0, SFR 98h) or TI_0 (SCON0.1, SFR 98h) flags.

ET1

Enable Timer 1 Interrupt. This bit controls the masking of the Timer 1 interrupt.

bit 3

0: Disable Timer 1 interrupt.

1: Enable interrupt requests generated by the TF1 flag (TCON.7, SFR 88h).

EX1

Enable External Interrupt 1. This bit controls the masking of external interrupt 1.

bit 2

0: Disable external interrupt 1.

1: Enable interrupt requests generated by the INT1 pin.

ET0

Enable Timer 0 Interrupt. This bit controls the masking of the Timer 0 interrupt.

bit 1

0: Disable all Timer 0 interrupts.

1: Enable interrupt requests generated by the TF0 flag (TCON.5, SFR 88h).

EX0

Enable External Interrupt 0. This bit controls the masking of external interrupt 0.

bit 0

0: Disable external interrupt 0.

1: Enable interrupt requests generated by the INT0 pin.
