8.2.31 Set Multiple Mode (C6h)

This command enables the drive to perform Read and Write Multiple operations and establishes the block count for these commands.

The Sector Count register is loaded with the number of sectors per block. Drives support block sizes of 2, 4, 8, and 16 sectors. If the Sector Count register contains a valid value and the block count is supported, the value is loaded for all subsequent Read Multiple and Write Multiple commands and execution of those commands is enabled. If a block count is not supported, an Aborted Command error is posted, and Read Multiple and Write Multiple commands are disabled.

At power-on, or after a hardware reset, the default mode is Read and Write Multiple disabled. And on software reset, the default mode of Read and Write Multiple will not be changed.

8.2.32 Sleep (E6h)

This command is the only way to cause the drive to enter Sleep Mode. The drive is spun down, and when it is stopped, BSY is cleared, an interrupt is generated, and the interface becomes inactive.

The only way to recover from Sleep mode without a reset or power-on is for the host to issue a software reset. A drive shall not power-on in Sleep Mode nor remain in Sleep Mode following a reset sequence. If the drive is already spun down, the spin down sequence is not executed.

8.2.33 Standby (E2h)

This command causes the drive to set BSY, enter the Standby Mode, clear BSY, and assert INTRQ. INTRQ is asserted even though the device may not have fully transitioned to Standby Mode.

If the Sector Count register is non-zero, then the Standby Timer is enabled. The value in the Sector Count register shall be used to determine the time programmed into the Standby Mode.

The value in the Sector Count register when the STANDBY command is issued shall determine the time period programmed into the Standby Timer.
