The table given below provides a list of the registers for the embedded advanced features

page 1. These registers are accessible when PAGE_SEL[3:0] are set to 0001 in

PAGE_SEL (02h).

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
