Power Up Vs. Power Down Timing - Quarch Technology Torridon HS Technical Manual

Power Up vs. Power Down Timing

Each control source is always configured with power-up parameters; the power-down profile is
automatically generated by the module, and is the mirror image of the power up:
HOT_SWAP
BUSY
CONTROL SOURCE S1
CONTROL_SOURCE S2
CONTROL_SOURCE S3
CONTROL_SOURCE S4
Power Down Times are automatically generated by the module but can be calculated as follows:
T = Largest Time Period
MAX
= the largest value from:
Power Down Delay T
X
If you require a different power down sequence then you can alter any of the source timing values,
pin bounce or signal assignments while the drive is in the plugged state. When you initiate the 'pull'
action, the new settings will be used.
