5.1

The internal Configuration registers are initialized to

their default values under two different conditions:

• After 220 clock cycles of delay from the Power-on

Reset (POR).

• Resetting the hardware reset pin (RESET).

Figures 2-3 and 2-4 show the timing details.

5.2

Configuration Registers

The internal registers are mapped from Addresses

0x00 – 0x15D.

These

user

registers

are

not

sequentially

located.

Some

user

Configuration

registers include factory-controlled bits. The factory-

controlled bits should not be overwritten by the user.

All user Configuration registers are read/write, except

for the last four registers, which are read-only. Each

their default values are loaded during the power-up

sequence or by using the hardware RESET pin. All

registers are accessible by the SPI command using the

memory map, and Registers 5-1 – 5-83 show the

details of the register bit functions.
