Registers marked as Reserved must not be changed. Writing to those registers may cause permanent damage to

the device.

The content of the registers that are loaded at boot should not be changed. They contain the factory calibration

values. Their content is automatically restored when the device is powered up.

Write procedure example:

Example: write value 06h register at address 84h (PEDO_DEB_STEPS_CONF) in Page 1

1. Write bit FUNC_CFG_EN = 1 in FUNC_CFG_ACCESS (01h)

// Enable access to embedded functions registers

2. Write bit PAGE_WRITE = 1 in PAGE_RW (17h) register

// Select write operation mode

3. Write 0001 in PAGE_SEL[3:0] field of register PAGE_SEL (02h)

// Select page 1

4. Write 84h in PAGE_ADDR register (08h)

// Set address

5. Write 06h in PAGE_DATA register (09h)

// Set value to be written

6. Write bit PAGE_WRITE = 0 in PAGE_RW (17h) register

// Write operation disabled

7. Write bit FUNC_CFG_EN = 0 in FUNC_CFG_ACCESS (01h)

// Disable access to embedded functions registers

Read procedure example:

Example: read value of register at address 84h (PEDO_DEB_STEPS_CONF) in Page 1

1. Write bit FUNC_CFG_EN = 1 in FUNC_CFG_ACCESS (01h)

// Enable access to embedded functions registers

2. Write bit PAGE_READ = 1 in PAGE_RW (17h) register

// Select read operation mode

3. Write 0001 in PAGE_SEL[3:0] field of register PAGE_SEL (02h)

// Select page 1

4. Write 84h in PAGE_ADDR register (08h)

// Set address

5. Read value of PAGE_DATA register (09h)

// Get register value

6. Write bit PAGE_READ = 0 in PAGE_RW (17h) register

// Read operation disabled

7. Write bit FUNC_CFG_EN = 0 in FUNC_CFG_ACCESS (01h)

// Disable access to embedded functions registers

Note:

Steps 1 and 2 of both procedures are intended to be performed at the beginning of the procedure. Steps 6 and 7

of both procedures are intended to be performed at the end of the procedure. If the procedure involves multiple

operations, only steps 3, 4 and 5 must be repeated for each operation. If, in particular, the multiple operations

involve consecutive registers, only step 5 can be performed.
