Lock Register
Description
0 Pin Control Register bits [15:0] are not locked.
1 Pin Control Register bits [15:0] are locked and cannot be updated until the next System Reset.
This read-only field is reserved and always has the value zero.
Pin Mux Control
The corresponding pin is configured as follows:
000 Pin Disabled (Analog).
001 Alternative 1 (GPIO).
010 Alternative 2 (chip specific).
011 Alternative 3 (chip specific).
100 Alternative 4 (chip specific).
101 Alternative 5 (chip specific).
110 Alternative 6 (chip specific).
111 Alternative 7 (chip specific / JTAG / NMI).
This read-only field is reserved and always has the value zero.
Drive Strength Enable
Drive Strength configuration is valid in all digital pin muxing modes.
0 Low drive strength is configured on the corresponding pin, if pin is configured as a digital output.
1 High drive strength is configured on the corresponding pin, if pin is configured as a digital output.
Open Drain Enable
Open Drain configuration is valid in all digital pin muxing modes.
0 Open Drain output is disabled on the corresponding pin.
1 Open Drain output is enabled on the corresponding pin, provided pin is configured as a digital output.
Passive Filter Enable
Passive Filter configuration is valid in all digital pin muxing modes.
0 Passive Input Filter is disabled on the corresponding pin.
1 Passive Input Filter is enabled on the corresponding pin, provided pin is configured as a digital input.
A low pass filter (10 MHz to 30 MHz bandwidth) is enabled on the digital input path. Disable the
Passive Input Filter when supporting high speed interfaces (> 2 MHz) on the pin.
This read-only field is reserved and always has the value zero.
