Reserved - do not blow this bit.
Blow to indicate external pull-ups implemented for SSP3.
Blow to indicate external pull-ups implemented for SSP2.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE7 and GPMI_RDY7 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE6 and GPMI_RDY6 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE5 and GPMI_RDY5 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE4 and GPMI_RDY4 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE3 and GPMI_RDY3 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE2 and GPMI_RDY2 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE1 and GPMI_RDY1 pins.
If the bit is blown then ROM NAND driver will enable internal pull-up for GPMI_CE0 and GPMI_RDY0 pins.
If this bit is blown then internal pull-ups for SSP are neither enabled nor disabled. This bit is used only if
external pull-ups are implemented and ROM1:18 and/or ROM1:17 are blown.
Blow to indicate external pull-ups implemented for SSP1.
