I am using MC68EN360 for one of the project. I wanted to interface ethernet chip (ENC28J60) using SPI with M68K.
I have configured the clock of SPI to 6.25Mhz and the SPI mode '0' is set . The problem i am facing here is for the consecutive write (SPI write) there is a delay of around ~500us(micro seconds) and same delay is observed for consecutive read (SPI read) as well. Due to this i am not able receive/transmit ethernet packets at faster rate.
I have looked into the usermanual of MC68EN360 did not find any information on the minimum delay between write/read. want to know is this the known behavior or any configuration issue.?
