i hope you dont mind, that i am writing in english.
i am looking for information on the hitachi-IC: "HD46510".
it is a 42-pin DIP and was produced around 1982;it is used together
with a hd6802W-microcontroller in the ECU of my nissan pulsar.
i think its function is a multiplexed A/D-converter, input/output,
timer..?
i hope anyone can help me or tell me where to find help...
thank you in advance

greetings from austria
