TPS65987D: SPI pin number error in datasheet

Part Number: TPS65987D

Hello,

Please can you confirm which SPI pin is the output (used to be called MOSI)

Fig 5-1 says POCI is on pin 37

Table 5-1 tells me that POCI is on pin 36.

It also says both POCI and PICO are inputs, which cannot be correct.

So which one is the output? (formerly called MOSI)

Thanks,

Fiona

Arda,

Thank you for your feedback. While I am waiting on the confirmation, I will relay your feedback to the relevant team and you can submit a document feedback using the "Submit Document Feedback" link in the footer of each page of the datasheet.

Again, thank you for your valuable feedback.

Regards.

Hi Fiona,

SPI_POCI (SPI_MISO) should be pin 36 and SPI_PICO (SPI_MOSI) should be pin 37.

The "input" in the 4th column indicates the state of the pin in the reset state (Reset State indicates the state of a given pin immediately following power application, prior to any configuration from firmware).

I will notify the relevant team on this error so this will be updated in the next release.

Regards.
