Preliminary
TS80C31X2
Table 7. Priority Level Bit Values
A low-priority interrupt can be interrupted by a high priority interrupt, but not by another low-priority interrupt.
A high-priority interrupt can’t be interrupted by any other interrupt source.
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 simultaneously, 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.
