Flash PCM Access area for calibration

Post by VX L67 Getrag »

For VX-VY eeprom section is it only between 0E00 to 0E3F or 0E00 to 0E7F & all the data before & after this before 1FFF is just learnt RAM?

Basically it uses that part of the bin to tell it what to access each section of the calibration?

Info here on the EEPROM (E00 to FFF).. https://pcmhacking.net/forums/viewtopi ... 502&p=6040

Everything else below 2000 is pretty much just RAM and CPU registers.

Thanks VL400,

I wasn't sure that was 100% correct as that was info from early stages of the development of these PCM's?

Do you have a full layout of what & where each section of the RAM is & same for the CPU registers?
