(2) READ MULTIPLE (X'C4') This command operates similarly to the READ SECTOR(S) command. The device does not generate an interrupt (assertion of the INTRQ signal) on each every sector. An interrupt is generated after the transfer of a block of sectors for which the number is specified by the SET MULTIPLE MODE command. 5-18 C141-E104-03EN
