If two interrupt requests of different priority levels are received simultaneously, the request of
higher priority level is serviced. If interrupt requests of the same priority level are received simul-
taneously, an internal polling sequence determines which request is serviced. Thus within each
priority level there is a second priority structure determined by the polling sequence.

EA
Enable All interrupt bit
Clear to disable all interrupts.
Set to enable all interrupts.
If EA=1, each interrupt source is individually enabled or disabled by setting or clearing its
own interrupt enable bit.
6
-
Reserved
The value read from this bit is indeterminate. Do not set this bit.
5
ET2
Timer 2 overflow interrupt Enable bit
Clear to disable timer 2 overflow interrupt.
Set to enable timer 2 overflow interrupt.
4
ES
Serial port Enable bit
Clear to disable serial port interrupt.
Set to enable serial port interrupt.
3
ET1
Timer 1 overflow interrupt Enable bit
Clear to disable timer 1 overflow interrupt.
Set to enable timer 1 overflow interrupt.

External interrupt 1 Enable bit
Clear to disable external interrupt 1.
Set to enable external interrupt 1.
1
ET0
Timer 0 overflow interrupt Enable bit
Clear to disable timer 0 overflow interrupt.
Set to enable timer 0 overflow interrupt.
0
EX0
External interrupt 0 Enable bit
Clear to disable external interrupt 0.
Set to enable external interrupt 0.
