Description

gpio0_out

R/W

Writes a logic signal to pin GPIO0; this is independent of

any other bit setting e.g., gpio0_mode.

gpio1_out

R/W

Writes a logic signal to pin GPIO1; this is independent of

any other bit setting e.g., gpio1_mode.

gpio2_out

R/W

Writes a logic signal to pin GPIO2; this is independent of

any other bit setting e.g., gpio2_mode.

gpi_en

R/W

Enables the GPI input. Set to 1 if used for strobe trigger.

0 = input disabled

1 = input enabled; can be used for strobe trigger

gpi_curr30_en

R/W

Enables the CURR30 input.

0 = input disabled

1 = input enabled

gpi_curr31_en

R/W

Enables the CURR31 input.

0 = input disabled

1 = input enabled

gpi_curr32_en

R/W

Enables the CURR32 input.

0 = input disabled

1 = input enabled

gpi_curr33_en

R/W

Enables the CURR33 input.

0 = input disabled

1 = input enabled

Description

gpio0_in

N/A

Reads a logic signal from pin GPIO0; this is independent of

any other setting e.g., bits gpio1_mode.

gpio1_in

N/A

Reads a logic signal from pin GPIO1; this is independent of

any other setting e.g., bits gpio1_mode.

gpio2_in

N/A

Reads a logic signal from pin GPIO2; this is independent of

any other setting e.g., bits gpio1_mode.

gpi_in

N/A

Reads a logic signal from pin GPI; if gpi_en=1

curr30_in

N/A

Reads a logic signal from pin CURR30; if gpi_curr30_en=1

curr31_in

N/A

Reads a logic signal from pin CURR31; if gpi_curr31_en=1

curr32_in

N/A

Reads a logic signal from pin CURR32; if gpi_curr32_en=1

curr33_in

N/A

Reads a logic signal from pin CURR33; if gpi_curr33_en=1
