General discussion • Where can I find a Pico Pinout that uses the new standard SPI-abbreviations?

The datasheet of the RaspBerry Pi pico that can be found here
https://datasheets.raspberrypi.com/pico ... asheet.pdf

uses non-standard abbreviations for the SPI-pins.
It looks like this


To me these abbreviations are confusing

Where can I find a pin-out of the RaspBerry Pi pico that uses the new standard abbreviations ?

which are
SPI - New signal names:
SDO – Serial Data Out. An output signal on a device where data is sent out to another SPI device.
SDI – Serial Data In. An input signal on a device where data is received from another SPI device.
CS – Chip Select. Activated by the controller to initiate communication with a given peripheral.
PICO (peripheral in/controller out). For devices that can be either a controller or a peripheral; the signal on which the device sends output when acting as the controller, and receives input when acting as the peripheral.
POCI (peripheral out/controller in). For devices that can be either a controller or a peripheral; the signal on which the device receives input when acting as the controller, and sends output when acting as the peripheral.
