Main Status Register

Address 3F4 READ ONLY

The Main Status Register is a read-only register and indicates the status of the disk controller. The Main

Status Register can be read at any time. The MSR indicates when the disk controller is ready to receive

data via the Data Register. It should be read before each byte transferring to or from the data register

except in DMA mode. No delay is required when reading the MSR after a data transfer.

Reserved Reserved

BIT 0 鈥?1 DRV x BUSY

These bits are set to 1s when a drive is in the seek portion of a command, including implied and

overlapped seeks and recalibrates.

BIT 4 COMMAND BUSY

This bit is set to a 1 when a command is in progress. This bit will go active after the command byte has

been accepted and goes inactive at the end of the results phase. If there is no result phase (Seek,

Recalibrate commands), this bit is returned to a 0 after the last command byte.

BIT 5 NON-DMA

Reserved, read 鈥?鈥? This part does not support non-DMA mode.

BIT 6 DIO

Indicates the direction of a data transfer once a RQM is set. A 1 indicates a read and a 0 indicates a write

is required.

BIT 7 RQM

Indicates that the host can transfer data if set to a 1. No access is permitted if set to a 0.
