I am attempting to communicate with a Microchip 25AA080A, SPI based EERPOM from an MC9S12E128. The code has been pared down to a simple read of the status register instruction. The serial timing of the CS, MOSI and SCK are textbook perfect and far inside the spec of the chip but it won't respond on the serial out pin.
CPOL and CPHA = 0
VCC = 3.4V
Serial Input Voltage High = 3.37V
/WP, /HOLD are tied to VCC
Has anyone had experience with this device?
