Configuration
- HOLD active
- When true, pad 9 (HOLD) is tied to GND, pausing all SPI transactions on the bus (without resetting state). When false (default), pad 9 floats and the chip's internal pull-up keeps it deasserted. Only meaningful in SPI mode (in QSPI mode pad 9 is IO3).
- Write-protect
- When true, pad 6 (WP) is tied to GND, write-protecting the lower portion of memory per the chip's status register. When false (default), pad 6 floats and the chip's internal pull-up keeps it deasserted (writes allowed). Only meaningful in SPI mode (in QSPI mode pad 6 is IO2).
