78M6612 Data Sheet
3.8 Connecting 3-Wire EEPROMs
µ
shown in
must be connected to a vacant DIO pin of the 78M6612. A pull-up resistor of roughly 10 kΩ to V3P3D
(to ensure operation in BROWNOUT mode) should be used for the DI/DO signals, and the CS pin should
be pulled down with a resistor to prevent that the 3-wire device is selected on power-up, before the
78M6612 can establish a stable signal for CS. The DIO_EEX register in I/O RAM must be set to 10 in
order to convert the DIO pins DIO4 and DIO5 to
necessary.
3.9 UART0 (TX/RX)
The RX pin should be pulled down by a 10 kΩ resistor and additionally protected by a 100 pF ceramic
capacitor, as shown in
70
Wire EEPROMs and other compatible devices should be connected to the DIO pins DIO4 and DIO5, as
Figure
33. DIO5 connects to both the DI and DO pins of the three-wire device. The CS pin
