Media ID1 Media ID0 (Bit 7, 6):
These two bits are read only. These two bits reflect the value of CR8 bit 3, 2.
Drive type ID1 Drive type ID0 (Bit 5, 4):
These two bits reflect two of the bits of CR7. Which two bits are reflected depends on the last drive
selected in the DO REGISTER.
Floppy Boot drive 1, 0 (Bit 3, 2):
These two bits reflect the value of CR8 bit 1, 0.
Tape Sel 1, Tape Sel 0 (Bit 1, 0):
These two bits assign a logical drive number to the tape drive. Drive 0 is not available as a tape drive and
is reserved as the floppy disk boot drive.

Main Status Register (MS Register) (Read base address + 4)
The Main Status Register is used to control the flow of data between the microprocessor and the
controller. The bit definitions for this register are as follows:
6
5
4
3
2
1
0
FDD 0 Busy, (D0B = 1), FDD number 0 is in the SEEK mode.
FDD 1 Busy, (D1B = 1), FDD number 1 is in the SEEK mode.
FDD 2 Busy, (D2B = 1), FDD number 2 is in the SEEK mode.
FDD 3 Busy, (D3B = 1), FDD number 3 is in the SEEK mode.
FDC Busy, (CB). A read or write command is in the process when CB = HIGH.
Non-DMA mode, the FDC is in the non-DMA mode, this bit is set only during the
Transition to LOW state indicates execution phase has ended.
DATA INPUT/OUTPUT, (DIO). If DIO= HIGH then transfer is from Data Register to the processor.
If DIO = LOW then transfer is from processor to Data Register.
Request for Master (RQM). A high on this bit indicates Data Register is ready to send or receive data to or from the processor.
