SCRTCH_PAD

Scratch pad

CLASS_B_SKT3

Socket 3 Class B Smart Card support. Since socket 3 is not implemented in the controller, this

bit is a read-only 0.

CLASS_B_SKT2

Socket 2 Class B Smart Card support. Since socket 2 is not implemented in the controller, this

bit is a read-only 0.

CLASS_B_SKT1

Socket 1 Class B Smart Card support. When this bit is set to 1, socket 1 supports Class B Smart

Cards.

CLASS_B_SKT0

Socket 0 Class B Smart Card support. When this bit is set to 1, socket 0 supports Class B Smart

Cards.

CLASS_A_SKT3

Socket 3 Class A Smart Card support. Since socket 3 is not implemented in the controller, this

bit is a read-only 0.

CLASS_A_SKT2

Socket 2 Class A Smart Card support. Since socket 2 is not implemented in the controller, this

bit is a read-only 0.

CLASS_A_SKT1

Socket 1 Class A Smart Card support. When this bit is set to 1, socket 1 supports Class A Smart

Cards.

CLASS_A_SKT0

Socket 0 Class A Smart Card support. When this bit is set to 1, socket 0 supports Class A Smart

Cards.

EMVIF_EN_SKT3

Socket 3 EMV interface enable. Since socket 3 is not implemented in the controller, this bit is

a read-only 0.

EMVIF_EN_SKT2

Socket 2 EMV interface enable. Since socket 2 is not implemented in the controller, this bit is

a read-only 0.

EMVIF_EN_SKT1

Socket 1 EMV interface enable. When this bit is set to 1, the internal EVM interface for socket

1 is enabled.

EMVIF_EN_SKT0

Socket 0 EMV interface enable. When this bit is set to 1, the internal EVM interface for socket

0 is enabled.

GPIO_EN_SKT3

Socket 3 GPIO enable. Since socket 3 is not implemented in the controller, this bit is a read-only

GPIO_EN_SKT2

Socket 2 GPIO enable. Since socket 2 is not implemented in the controller, this bit is a read-only

GPIO_EN_SKT1

Socket 1 GPIO enable. When this bit is set to 1, the SC_GPIOs for socket 1 are enabled.

GPIO_EN_SKT0

Socket 0 GPIO enable. When this bit is set to 1, the SC_GPIOs for socket 0 are enabled.

PCMCIA_MODE_SKT3

Socket 3 PCMCIA mode. Since socket 3 is not implemented in the controller, this bit is a

read-only 0.

PCMCIA_MODE_SKT2

Socket 2 PCMCIA mode. Since socket 2 is not implemented in the controller, this bit is a

read-only 0.

PCMCIA_MODE_SKT1

Socket 1 PCMCIA mode. Since socket 1 is implemented as a dedicated socket in the controller,

this bit returns 1 when read.

PCMCIA_MODE_SKT0

Socket 0 PCMCIA mode. Since socket 0 is implemented as a dedicated socket in the controller,

this bit returns 1 when read.

PME_SUPPORT_SKT3

Socket 3 PME support. Since socket 3 is not implemented in the controller, this bit is a read-only

PME_SUPPORT_SKT2

Socket 2 PME support. Since socket 2 is not implemented in the controller, this bit is a read-only

PME_SUPPORT_SKT1

Socket 1 PME support. When this bit is set to 1, socket 1 card insertions cause a PME event.

PME_SUPPORT_SKT0

Socket 0 PME support. When this bit is set to 1, socket 0 card insertions cause a PME event.

SKT3_EN

Socket 3 enable. Since socket 3 is not implemented in the controller, this bit is a read-only 0.

SKT2_EN

Socket 2 enable. Since socket 2 is not implemented in the controller, this bit is a read-only 0.

SKT1_EN

Socket 1 enable. When this bit is set to 1, socket 1 is enabled.

SKT0_EN

Socket 0 enable. When this bit is set to 1, socket 0 is enabled.
