CURRENT_STRENGTH_NEW
CURRENT_STRENGTH_NEW
Type
Sets the drive strength of a pin. Specify a number (in mA), MIN, or MAX for output or
bidirectional pins that support programmable drive strength. Refer to the family data
sheet for which drive strengths are allowed for each I/O standard. This option is
ignored if it is applied to anything other than an output or bidirectional pin.
This option specifies a current strength setting for the single-ended output buffer of a
pin. Since an input-only pin does not use single-ended output buffer, this option is
ignored on such pin. This option is not supported on a pin with I/O standard which
uses true differential output buffer such as LVDS. Some differential I/O standards are
implemented with two single-ended output buffers and therefore this option may be
supported. Refer to the family data sheet for which I/O standards support
programmable drive strengths. This option can only be supported on pin locations
that support programmable drive strength. Dedicated programming pins, such as
TDO, do not support programmable drive strength. If output termination is enabled
on a pin, then this current strength assignment should not be used on the pin.
