V600/V620 ID Controller Protocol
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.
Send Data Word Allocation (2nd Operand of PMCR)
First word of send
data
+(4(N-1)+2)
+(4(N-1)+3)
+(4(N-1)+4)
+(4(N-1)+5)
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
leading 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.
