This bit globally enables/disables all interrupts. It overrides the individual interrupt mask
settings.
0: Disable all interrupt sources.
1: Enable each interrupt according to its individual mask setting.
IEGF0: General Purpose Flag 0.
This is a general purpose flag for use under software control.
This bit sets the masking of the Timer 2 interrupt.
0: Disable all Timer 2 interrupts.
1: Enable interrupt requests generated by the TF2 flag (T2CON.7)
This bit sets the masking of the Serial Port (UART) interrupt.
0: Disable all UART interrupts.
1: Enable interrupt requests generated by the R1 flag (SCON.0) or T1 flag (SCON.1).
This bit sets the masking of the Timer 1 interrupt.
0: Disable all Timer 1 interrupts.
1: Enable interrupt requests generated by the TF1 flag (TCON.7).
This bit sets the masking of external interrupt 1.
0: Disable external interrupt 1.
1: Enable interrupt requests generated by the /INT1 pin.
This bit sets the masking of the Timer 0 interrupt.
0: Disable all Timer 0 interrupts.
1: Enable interrupt requests generated by the TF0 flag (TCON.5).
This bit sets the masking of external interrupt 0.
0: Disable external interrupt 0.
1: Enable interrupt requests generated by the /INT0 pin.
EA: Enable All Interrupts.
ET2: Enable Timer 2 Interrupt.
ES: Enable Serial Port (UART) Interrupt.
ET1: Enable Timer 1 Interrupt.
EX1: Enable External Interrupt 1.
ET0: Enable Timer 0 Interrupt.
EX0: Enable External Interrupt 0.
