TMS570LC4357: What does ZD mean?

Hi Lucas,

ZD means Z-Drive,

• Z-drive: This refers to a specific type of output buffer or driver used by TI. It's a robust, general-purpose I/O (GPIO) output buffer, usually a push-pull configuration, designed to provide a specified current.
• 2-mA ZD: This indicates that the pin, when configured as an output, has a typical drive strength of 2 milliamperes (mA) using the Z-drive buffer type. This means it can typically source (provide) or sink (draw) up to 2mA of current.

So, "2-mA ZD" describes the current capability and the type of output buffer for the pin.
