ssp_read_word(9)

✨ NAME ✨

okay bestie, welcome to ssp_read_word(9) from the Kernel API Manual 💖 — this one is all about reading a word from the SSP port.

🌸 SYNOPSIS 🌸

int ssp_read_word (u16 *data );

🎀 ARGUMENTS 🎀

• data — -- undescribed -- ... yep, the docs are literally leaving us on read here 🙈😭

🦋 DESCRIPTION 🦋

So this function waits for a data word to show up in the SSP receive FIFO, then returns the received data. The data is LSB justified. Slay. ✨

💅 NOTE 💅

⚠️ Currently, if data is not expected to be received, this function will wait for ever. Not the vibe, bestie — it’s giving eternal waiting room 😭💀

The caller is expected to perform the necessary locking. Lock it down, okay? 🔒👑

🔥 RETURN 🔥

• -ETIMEDOUT — timeout occurred
• 16-bit data — success
