I think EEPROM in general is working. Do you have specific EEPROM to try?

for eeprom, i see SPI and I2C protocol support, but not MICROWIRE.

here is specific eeprom:

MICROWIRE protocol is subset of SPI, but not the same protocol (data latch is different).

I see. I do not think USB JTAG NT can support it. The slowest clock is 6M. But I will keep this in mind.

Microwire might be supported in future project.
