In the `Get started with MicroPython on Raspberry Pi Pico' book there is this great explanation of the SPIx_Rx and SPIx_Tx nomenclature: >SPI TERMINOLOGY SPI requires four connections: one that...
The [Raspberry Pi Pico C/C++ SDK](https://datasheets.raspberrypi.com/pico/) book mentiones `sm_config_out_shift` on page 42. It should be `sm_config_set_out_shift` (added `_set`). The book version I'm using is ``` build-date: 2022-06-30 build-version: c182344-clean ```
This is following up on my post in the forum at https://forums.raspberrypi.com/viewtopic.php?p=2050416 In short: unless I artificially slow down writing data to the UART FIFO, 15-byte chunks of my outgoing...
There are a couple issues I think I've found with the HCD documentation, and a couple of queries regarding the behavior of the PHY. Firstly, in section 4.1.2.7.2. HOST CONTROLLER...
In the **RP2040 Datasheet** with build-date: _2022-06-17_ and build-version: _7028f9f-clean_ the table of contents, "4.3.14. **IC_CLK** Frequency Configuration" is described but its source is never defined. No mention of it...

In the RP2040 Datasheet Page 417 in Figure 59 in the DMA Interface (bottom-left of figure) the first **UARTTXDMABREQ** should be the Receive Burst Request **UARTRXDMABREQ**. If you look at...
Some clarification in the the datasheet would be appreciated for the handling of USB OUT packets while in device mode. For the buffer control register section `4.1.2.5.4`: 1. Are bits...
## Summary The XOSC_STATUS_FREQ_RANGE bits (bits 0 and 1) in the XOSC_STATUS register are documented to "always read 0". However, on real hardware (RP2040 on a Raspberry Pi Pico), the...
The pico-w datasheet doesn't mention that the cyw43 driver utilises one state machine and 22/32 instructions for that PIO ... meaning you have fewer PIO resources should you be using...
