Polling Auto-read (Hexadecimal) (Sequence No. 514)

This sequence is used when the number of Heads to be read from the Carrier is from 1 to 8.

Receive Data Word Allocation (3rd Operand of PMCR)

None.

Note 1. Execute Sequence No. 514 before executing Sequence No. 515, 516, 517.

2.Execute Sequence No. 544 (Polling Auto-read Command Processing Cancel) to cancel the polling auto-read.

Polling Auto-read Sub-command (Hexadecimal/2) (Sequence No. 515)

This sequence is used when the maximum number of Heads to be read from the Carrier is 2. Up to 60 bytes of data can be read for each Read/Write Head.

Send Data Word Allocation (2nd Operand of PMCR)

The send data word allocation is similar to that of Sequence No. 505 (Read (Hexadecimal/2)). However, the lead- ing address No. and number of read bytes are not used and will be the value specified for sequence #514.

Receive Data Word Allocation (3rd Operand of PMCR)

The receive data word allocation is similar to that of Sequence No. 505 (Read (Hexadecimal/2)).

Note 1. Execute Sequence No. 514 before executing Sequence No. 515.
