d.
IRQ and DMA Enable and Disable: Any time the IRQ or DACK for a logical block is
disabled by a register bit in that logical block, the IRQ and/or DACK must be disabled. This
is in addition to the IRQ and DACK disabled by the Configuration Registers (active bit or
address not valid).
FDC: For the following cases, the IRQ and DACK used by the FDC are disabled (high
impedance). Will not respond to the DREQ
Digital Output Register (Base+2) bit D3 (DMAEN) set to "0".
The FDC is in power down (disabled).
Serial Port 1 and 2:
Modem Control Register (MCR) Bit D2 (OUT2) - When OUT2 is a logic "0", the serial port
interrupt is forced to a high impedance state - disabled.
Parallel Port:
I.
ii.
Keyboard Controller: Refer to the KBD section of this spec.
(FROM ECR REGISTER)
SPP and EPP modes: Control Port (Base+2) bit D4 (IRQE) set to "0", IRQ is
disabled (high impedance).
