7.32 PSR and Power Supply Configuration (address 34h)

7.32.1 Power Supply Rejection Enable (PSR_EN)

Default = 0

0 - disable

1 - enable

Function:

Enables the on-card and internal power supply rejection circuitry. This bit will cause the PSR_EN output

signal to change logic level. A ‘0’b in this bit will cause the PSR_EN to drive a logic low. A ‘1’b will drive a

logic high.
