Note 8.12 If MT is set to "1" and the SC value is greater than the number of remaining formatted sectors on Side 0,
verifying will continue on Side 1 of the disk.
8.7.7.7 Format A Track
The Format command allows an entire track to be formatted. After a pulse from the nINDEX pin is
detected, the FDC starts writing data on the disk including gaps, address marks, ID fields, and data fields
per the IBM System 34 or 3740 format (MFM or FM respectively). The particular values that will be written
to the gap and data field are controlled by the values programmed into N, SC, GPL, and D which are
specified by the host during the command phase. The data field of the sector is filled with the data byte
specified by D. The ID field for each sector is supplied by the host; that is, four data bytes per sector are
needed by the FDC for C, H, R, and N (cylinder, head, sector number and sector size respectively).
After formatting each sector, the host must send new values for C, H, R and N to the FDC for the next
sector on the track. The R value (sector number) is the only value that must be changed by the host after
each sector is formatted. This allows the disk to be formatted with nonsequential sector addresses
(interleaving). This incrementing and formatting continues for the whole track until the FDC encounters a
pulse on the nINDEX pin again and it terminates the command.
Table 8.29 contains typical values for gap fields which are dependent upon the size of the sector and the
number of sectors on each track. Actual values can vary due to drive electronics.
