Function Documentation

syter_efuse_dump()

void syter_efuse_dump

(

void

)

Dump the contents of the eFuse memory.

This function outputs the current contents of the eFuse memory for diagnostic purposes. The format of the output is implementation-dependent.

syter_efuse_read()

uint32_t syter_efuse_read

(

uint32_t

offset

)

Read a value from the eFuse memory.

This function reads a 32-bit value from the specified eFuse offset.

Parameters

offset

The offset in the eFuse memory from which to read the value.

Returns

The 32-bit value read from the specified eFuse offset.

syter_efuse_write()

void syter_efuse_write	(	uint32_t	offset,
		uint32_t	value
	)

Write a value to the eFuse memory.

This function writes a 32-bit value to the specified eFuse offset.

Parameters

offset	The offset in the eFuse memory to which the value will be written.
value	The 32-bit value to be written to the eFuse memory.
