Table 20 - Description of Command Symbols
NAME
Overwrite
The bits D0-D3 of the Perpendicular Mode Command can only be
modified if OW is set to 1. OW is defined in the Lock command.
Present Cylinder
Number
Interrupt 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
Relative 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
Write Gate
Alters timing of WE to allow for pre-erase loads in perpendicular
drives.
SYMBOL
OW
DESCRIPTION
PCN
The current position of the head at the completion of Sense
POLL
PRETRK
Programmable from track 00 to FFH.
R
RCN
Relative cylinder offset from present cylinder as used by the
SC
The number of sectors per track to be initialized by the Format
SK
SRT
ST0
ST1
ST2
ST3
WGATE
Registers within the FDC which store status information after a
command has been executed. This status information is available
to the host during the result phase after command execution.
