8-5-1-19. STANDBY IMMEDIATE - 94h, E0h
This command is used to cause TC6374AF to set BSY and enter the Standby mode. Then, it clears BSY and
generates an interrupt. The interrupt is generated even if TC6374AF is not completely enter the Standby
mode. TC6374AF moves, immediately after this command is issued, to the power-down mode. The
oscillation will stop. If, once the power-down is performed, the command is accepted, then auto-powerdown
sequence starts based on the value of Sector Count Register set by STANDBY and IDLE commands. Even
during the power-down operation, the state can accept ATA command.
