Table 17 – Description of Command Symbols
SYMBOL
MT
NAME
Multi-Track
Selector
DESCRIPTION
When set, this flag selects the multi-track operating mode. In this
mode, the FDC treats a complete cylinder under head 0 and 1 as a
single track. The FDC operates as this expanded track started at the
first sector under head 0 and ended at the last sector under head 1.
With this flag set, a multitrack read or write operation will
automatically continue to the first sector under head 1 when the FDC
finishes operating on the last sector under head 0.
Sector Size Code This specifies the number of bytes in a sector. If this parameter is
"00", then the sector size is 128 bytes. The number of bytes
transferred is determined by the DTL parameter. Otherwise the
sector size is (2 raised to the "Nth" power) times 128. All values up
to "07" hex are allowable. "07"h would equal a sector size of 16k. It
is the user's responsibility to not select combinations that are not
possible with the drive.

Non-DMA Mode
Flag
Overwrite
The bits D0-D3 of the Perpendicular Mode Command can only be
modified if OW is set to 1. OW id defined in the Lock command.
Present Cylinder
Number
Status command.
Polling Disable
When set, the internal polling routine is disabled. When clear, polling
is enabled.
Precompensation
Start Track
Number
Sector Address
The sector number to be read or written. In multi-sector transfers,
this parameter specifies the sector number of the first sector to be
read or written.
Relative Cylinder
Number
Seek command.
Number of
Sectors Per Track
command. The number of sectors per track to be verified during a
Verify command when EC is set.
Skip Flag
When set to 1, sectors containing a deleted data address mark will
automatically be skipped during the execution of Read Data. If Read
Deleted is executed, only sectors with a deleted address mark will be
accessed. When set to "0", the sector is read or written the same as
the read and write commands.
Step Rate Interval The time interval between step pulses issued by the FDC.
Programmable from 0.5 to 8 milliseconds in increments of 0.5 ms at
the 1 Mbit data rate. Refer to the SPECIFY command for actual
delays.
Status 0
Status 1
Status 2
Status 3
N
NCN
The desired cylinder number.
ND
Write ‘0’. This part does not support non-DMA mode.
OW
PCN
The current position of the head at the completion of Sense Interrupt
POLL
PRETRK
Programmable from track 00 to FFH.
R
RCN
Relative cylinder offset from present cylinder as used by the Relative
SC
The number of sectors per track to be initialized by the Format
SK
SRT
ST0
ST1
ST2
ST3
Registers within the FDC that store status information after a
command has been executed. This status information is available to
the host during the result phase after command execution.
