A method of writing to a group of SRAM cells include sending a first write-enable signal to the cells via a first WL, sending a group of respective second write-enable signals to the respective cells, and, for each of the cells, preventing writing data to the cell if either of the ...

We also tried 720p30 (372 Mbps), which requires overvoltage on typical silicon (something you can do with one register write on RP2040): Honestly, this has shaken me. This is a silly amount of bandwidth for a tiny little microcontroller. Although it passes the eye mask and a few other...
Internal transmit and receive FIFOs with flush capability and support for byte, half-word, and word reads and writes. Data bit lengths from 5 to 9 bits. Programmable inter-packet transmit delays. Auto-baud detection with support for the LIN SYNC byte. ...
each bit plane (that is a uint32_t with all of the pin toggles for all 3 output ports for a particular pixel on a single bit plane, there are bit_depth number of bit planes per image) is updated atomically in a single write. This means there is no need for double buffering to ach...
Refer to the SRAM section on how to access the SRAM. Table 12. Command Word MSB DB15 DB14 DB13 DB12 … R/W A14 A13 A12 … LSB DB2 DB1 DB0 A2 A1 A0 When the first bit of the command byte is a logic low (R/W bit = 0), the SPI command is a write operation. In this ...
