Embedded advanced features pages

The table given below provides a list of the registers for the embedded advanced features page 0. These

registers are accessible when PAGE_SEL[3:0] are set to 0000 in PAGE_SEL (02h).

Note:

The content of these registers is loaded when the embedded functions are enabled by setting the

EMB_FUNC_EN bit to 1 in the CTRL4 (13h) register. The embedded functions must be enabled in order for

these registers to become accessible.

Reserved registers 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: write value 06h in register at address 5Eh (PEDO_DEB_STEPS_CONF) in Page 0

1. Write bit EMB_FUNC_REG_ACCESS = 1 in FUNC_CFG_ACCESS (3Fh) // Enable access to embedded functions

registers

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

// Select write operation mode

3. Write 0000 in PAGE_SEL[3:0] field of register PAGE_SEL (02h)

// Select page 0

4. Write 5Eh in PAGE_ADDRESS (08h) register

// Set address

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

// Set value to be written

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

// Write operation disabled

7. Write bit EMB_FUNC_REG_ACCESS = 0 in FUNC_CFG_ACCESS (3Fh) // Disable access to embedded functions
