Read procedure example: read value of 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_READ = 1 in PAGE_RW (17h) register

// Select read 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. Read value of PAGE_VALUE (09h) register

// Get register value

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

// Read operation disabled

7. Write bit EMB_FUNC_REG_ACCESS = 0 in FUNC_CFG_ACCESS (3Fh) // 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.
