Connecting Three-Wire EEPROMs
μ Wire EEPROMs and other compatible devices should be connected to the DIO pins DIO4 and DIO5, as
shown in Figure 13 and described below:

DIO5 connects to both the DI and DO pins of the three-wire device.
The CS pin must be connected to a vacant DIO pin of the 78M6618.
In order to prevent bus contention, a 10 k ? to resistor is used to separate the DI and DO signals.
The CS and CLK pins should be pulled down with resistors to prevent operation of the three-wire
device on power-up, before the 78M6618 can establish a stable signal for CS and CLK.
The DIO_EEX register in I/O RAM must be set to 2 (b10) in order to convert the DIO pins DIO4 and
DIO5 to μ Wire pins.
The μ -Wire EEPROM interface is only functional when MPU_DIV[2:0] = 000.
