Development Suggestions
1) Do review the Oxford OXCB950 UART documentation available through Axxon and also the following website:
http://www.oxsemi.com
2) Do note the EEPROM write delays required for a valid save. That is, methods including nested loops for delays
can be critical and cause an invalid write value to be saved as the host CPU system is ran at higher speeds. It is
recommended that a “guaranteed” safe slow delay be used to be universally compatible across the high speed
computer systems. Always verify the EEPROM save to confirm the EE value(s).
3) Do note that the EEPROM byte, low nibble is responsible for the configuration of 2 ports. This is since 2 bits
define an MIO pin setting. Be sure to mask the MIO pin status to index the proper pin configuration. That is, do not
alter the mode setting of the wrong port device.
4) Under NDA, Axxon can share source code under at least DOS for configuring this circuit board.
