type: 0x02 = 210

valid data_length is 16

data[] = 16 bytes of arbitrary user data to be stored in

the CFA633's non-volatile memory

The return packet will be:

type: 0x40 | 0x02 = 0x42 = 6610

data_length = 0

3 (0x03): Read User Flash Area

This command will read the User Flash Area and return the data to the host.

type: 0x03 = 310

valid data_length is 0

The return packet will be:

type: 0x40 | 0x03 = 0x43 = 6710

data_length = 16

data[] = 16 bytes user data recalled from the CFA633's

non-volatile memory

4 (0x04): Store Current State As Boot State

The CFA633 loads its power-up configuration from nonvolatile memory when power is applied. The CFA633 is

configured at the factory to display a “welcome” screen when power is applied. This command can be used to customize

the “welcome” screen, as well as the following items:



Characters shown on LCD, which are affected by:



command 6 (0x06): Clear LCD Screen (Pg. 42).



command 7 (0x07): Set LCD Contents, Line 1 (Pg. 42).



command 8 (0x08): Set LCD Contents, Line 2 (Pg. 43).



command 31 (0x1F): Send Data to LCD (Pg. 58).



Special character font definitions (command 9 (0x09): Set LCD Special Character Data (Pg. 43)).



Cursor position (command 11 (0x0B): Set LCD Cursor Position (Pg. 44)).



Cursor style (command 12 (0x0C): Set LCD Cursor Style (Pg. 44)).



Contrast setting (command 13 (0x0D): Set LCD Contrast (Pg. 44)).



Backlight setting (command 14 (0x0E): Set LCD & Keypad Backlight (Pg. 45)).



Fan power settings (command 17 (0x11): Set Fan Power (Pg. 45)).



Settings of any “live” displays (command 21 (0x15): Set Up Live Fan or Temperature Display (Pg. 49)).



Key press and release masks (command 23 (0x17): Configure Key Reporting (Pg. 50)).



Fan glitch delay settings (command 26 (0x1A): Set Fan Tachometer Glitch Filter (Pg. 52)).



ATX function enable and pulse length settings (command 28 (0x1C): Set ATX Power Switch

Functionality (Pg. 54)).



Baud rate (command 33 (0x21): Set Baud Rate (Pg. 58)).



GPIO settings (command 34 (0x22): Set or Set and Configure GPIO Pins (Pg. 58)).

You cannot store the fan or temperature reporting (although the live display of fans or temperatures can be

saved). You cannot store the fan fail-safe or host watchdog.The host software should enable these items once the

system is initialized and it is ready to receive the data.

type: 0x04 = 410
