Zpal-retention-register#

Defines a platform abstraction layer for the Z-Wave retention register.

How to use the retention register API

The retention register should support at least 32 x 32 bit registers which can be retained in deep sleep.

The following outlines an example of use:

  1. Store value in retention register using zpal_retention_register_write().

  2. Read value from retention register using zpal_retention_register_read().

Note:

  • Retention registers with index 0-15 are reserved for Z-Wave protocol code.

  • Retention registers are frequently written, so it is not recommended to use flash memory as storage.

Functions#

zpal_status_t
zpal_retention_register_read(uint32_t index, uint32_t *data)

Reads a 32-bit value from the specified retention register.

zpal_status_t
zpal_retention_register_write(uint32_t index, uint32_t value)

Write a 32-bit value to the specified retention register.

size_t
zpal_retention_register_count(void)

Get number of available retention registers.
