Function
Enables or disables external interrupt 0.
If EX0 = 0, external interrupt 0 is disabled.
Enables or disables the timer 0 overflow interrupt.
If ET0 = 0, the timer 0 interrupt is disabled.
Enables or disables external interrupt 1.
If EX1 = 0, external interrupt 1 is disabled.
Enables or disables the timer 1 overflow interrupt.
If ET1 = 0, the timer 1 interrupt is disabled.
Enables or disables the serial channel 0 interrupt.
If ES0 = 0, the serial channel 0 interrupt is disabled.
Enables or disables the timer 2 overflow or external reload interrupt.
If ET2 = 0, the timer 2 interrupt is disabled.
Enables or disables all interrupts. If EAL = 0, no interrupt will be acknowledged.
If EAL = 1, each interrupt source is individually enabled or disabled by setting or
clearing its enable bit.
This bit is not used for interrupt control.
