4.1.2. VPP Initialization

To enable VPP, following conditions shall be satisfied:

•

VCC must be successfully ramped prior to the start of ramping VPP.

•

VPP shall be ramped to meet its valid range prior to issuing the SET FEATURES (EFh) command to enable the

VPP functionality. The valid range is specified in Table 10 and Table 11.

•

The SET FEATURES (EFh) command shall be issued after the device is successfully powered-on.

•

Once VPP is enabled, VPP shall be maintained to keep the valid range.

Regarding power-down when VPP is enabled , following conditions shall be satisfied:

•

VPP must go down to 0V before VCC ramping down.

•

The device shall not be turned to power-down during busy period.

4.1.3. Single Channel Discovery

Host shall set to ’Low’ the CE which is to enable the target if connected, while all other CE are set to ’High’.

Host shall then issue the Reset command (FFh) to the target. Following the reset, the host should then issue the

Read ID command to the target. If the Host read out 6 cycles data by the Read ID command with address 00h, then

the corresponding target is connected. If the ID values are not returned or any error is encountered within the

sequence, then the corresponding target may not be connected properly and no further use of the target shall be

done.

4.1.4. Dual Channel Discovery

If there are dual channel in a package, host should issues the Reset command (FFh) to both channels to initialize

all LUNs. Note that the relationships are described between several CE and dual channels. See the Table 4 for

further information.

The sequence of initialization is the same as the sequence for single channel discovery. Host shall set to ’Low’ the

CE which is to enable the target if connected, while all other CE are set to ’High’. Host shall then issue the Reset

command (FFh) to the target. Following the reset, the host should then issue a Read ID command to the target. If

the Host read out 6 cycles data by the Read ID command with address 00h, then the corresponding target is

connected. If the ID values are not returned or any error is encountered within the sequence, then the

corresponding target may not be connected properly and no further use of the target shall be done.
