Used to configure the pad's drive strength, which, together
|
|
with the slew rate, affects the maximum frequency the pad's
|
|
output buffer can yield. If "normal" drive strength is used,
|
|
the maximum frequency will be lower as per the measurements
|
|
found in the SoC datasheet. Note that the TRM refers to the
|
|
"normal" drive strength as "standard". If unspecified, the
|
|
default will be "normal".

description: |
|
|
Used to configure the pad's slew rate, which affects the
|
|
maximum frequency the pad's output buffer can yield (
|
|
"fast" slew rate -> higher pad frequency, "slow" slew rate ->
|
|
lower pad frequency). Note that the TRM refers to the "fast"
|
|
slew rate as "standard". If unspecified, the default will be
|
|
"fast".
