□
For revision M and P
During power-off sequence, it is necessary to switch off VCC12 by driving PSC1 pin low by entering PSS mode (power domain 2 off).
If VCC12 needs to be switched off by other means, RSTX needs to be asserted before switching off VCC12 to inactivate the operation of
VCC12 supplied domain below the operation assurance range.
□
For except revision M and P
During power-off sequence, it is necessary to switch off VCC12 by driving PSC1 pin low by entering PSS mode (power domain 2 off).
If VCC12 needs to be switched off by other means, VCC5 needs ramping down to occur LVDH1 reset before switching off VCC12 t o
inactivate the operation of VCC12 supplied domain below the operation assurance range.
