Priority Level Structure
The following tables show the SFR IEN2, the priority level grouping (table 6-1) and the priority within
level (table 6-2). The principle of the priority level selection is identical to the SAB 80C517, i.e. a
pair or triple can be programmed to one of four priority levels.
Special Function Register IEN2
The reset value of IEN2 is XX00 00X0B.
Bit
Function
ES1
Enable serial interrupt of interface 1. Enables or disables the interrupt of serial
interface 1. If ES1 = 0, the interrupt is disabled.
ECMP
Enables interrupt on compare match in compare registers CM0 - CM7. If
ECMP = 0, the interrupt is disabled.
ECT
Enable compare timer interrupt. Enables or disables the interrupt at compare
timer overflow. If ECT = 0, the interrupt is disabled.
ECS
Enables interrupt on compare match in compare register COMSET. If ECS = 0,
the interrupt is disabled.
ECR
Enabled interrupt on compare match in compare register COMCLR. If ECR = 0,
the interrupt is disabled.
