Idle - 97H or E3H
This command causes the NAND Controller to set BSY, enter the Idle mode, clear BSY and generate
an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5
milliseconds and the automatic Power-down mode is enabled. If the sector count is zero, the automatic
Power-down mode is also enabled, the timer count is set to 3, with each count being 5 ms. Note that
this time base (5 msec) is different from the ATA specification.
Set-Sleep-Mode - 99H or E6H
This command causes the NAND Controller to set BSY, enter the Sleep mode, clear BSY and generate
an interrupt. Recovery from sleep mode is accomplished by simply issuing another command (a reset is
permitted but not required). Sleep mode is also entered when internal timers expire so the host does
not need to issue this command except when it wishes to enter Sleep mode immediately. The default
value for the timer is 15 milliseconds.
