SERIRQ CONFIGURATION REGISTERS

Note 5-4

The SIRQ Interrupt Configuration Registers are through the Host Access Port as 8-bit accesses. The

EC can access the SIRQ Interrupt Configuration Registers as 32-bit, 16-bit across 8-bit boundary or

as individual 8-bit accesses.

FRAME

These six bits select the Logical Device as the source for the interrupt.

This field defaults to 3Fh.

SELECT

If this bit is 0, the first interrupt signal from the Logical Device is selected for the SERIRQ vector. If this bit is 1, the second

interrupt signal from the Logical Device is selected. The KYBD controller is the only Logical Devices on the MEC1632

which has a second interrupt signal. For all other Logical Devices this field is ignored.

This field defaults to 1.
