Request Level

Select 0

on Vcc POR or

Reset_Drv

0x70 (R/W)

Bits[3:0] selects which interrupt level is used for

Interrupt 0.

0x00= no interrupt selected.

0x01= IRQ1

0x02= IRQ2

0x03= IRQ3

0x04= IRQ4

0x05= IRQ5

0x06= IRQ6

0x07= IRQ7

0x08= IRQ8

0x09= IRQ9

0x0A= IRQ10

0x0B= IRQ11

0x0C= IRQ12

0x0D= IRQ13

0x0E= IRQ14

0x0F= IRQ15

Note: All interrupts are edge high (except ECP/EPP)

Note:

An Interrupt is activated by setting the Interrupt Request Level Select 0 register to a non-zero

value AND :

for the FDC logical device by setting DMAEN, bit D3 of the Digital Output Register.

for the PP logical device by setting IRQE, bit D4 of the Control Port and in addition

for the PP logical device in ECP mode by clearing serviceIntr, bit D2 of the ecr.

for the Serial Port logical device by setting any combination of bits D0-D3 in the IER

and by setting the OUT2 bit in the UART's Modem Control (MCR) Register.

KYBD (refer to the KYBD controller section of this specification).

Note:

IRQ pins must tri-state if not used/selected by any Logical Device. Refer to Note A.
