Re: SD I/O 1.8MHz resonator

 

No, it is very tight on timing so that it can do full duplex bit bang.? But that runs on the 4Mhz Z80.? The 1.8Mhz is for the UART.

Josh: does your serial code do autobaud - i forget? If so it would probably be fine.

Good morning all,

This is proving to be another hard to find component, so I got a 2MHz one instead. If I understood correctly there's a direct correlation with the terminal baud rate provided by the UART. Would 200KHz make much diference?

Cheers
