Description
Reserved.
Output Enable for AFE Die Clock to Digital Die. The AFE die Pad P2.2 is internally
connected to the digital die internal Pad P1.10.
0 Disconnects AFE die clock path from digital die P1.10 internal pad.
1 Enables path for AFE die clock to digital die.
Pin Output Drive Enable. Each bit is set to enable the output for that particular pin.
These bits are cleared to disable the output for each pin.
Description
Reserved.
Pin Pull Enable. Each bit is set to enable the pull-up resistor and pull-down resistor
for that particular pin. The bit is cleared to disable the pull-up resistor and pull-down
resistor for each pin.
Description
Reserved.
Input Path Enable. Each bit is set to enable the input path and is cleared to disable
the input path for the GPIO pin.
Description
Reserved.
Registered Data Input. Each bit reflects the state of the GPIO pin if the corresponding
input buffer is enabled. If the pin input buffer is disabled, the value shown is zero.
Description
Reserved.
Data Out. Set by user code to drive the corresponding GPIO high. Cleared by user to
