Parameter bits that can be specified in some Command Bytes are:
YY b0=DMA_disable, b1-7=headload n*4ms (8" only)
* Format Track: output TR,HD,SC,SZ for each sector during execution phase* Read Track: reads NM sectors (starting with first sec past index hole)* Read ID: read ID bytes for current sec, repeated/undelayed read lists all IDs* Recalib: walks up to 77 tracks, 80tr-drives may need second recalib if failed* Seek/Recalib: All read/write commands will be disabled until succesful senseint* Senseint: Set's IC if unsuccesful (no int has occured) (until IC=0)
