Connecting Three-Wire EEPROMs
Wire EEPROMs and other compatible devices should be connected to the DIO pins DIO4 and DIO5, as
shown in Figure 34 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 71M6531.
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 71M6531 can establish a stable signal for CS and CLK.
The DIO_EEX[1:0] register in I/O RAM must be set to 2 (b10) in order to convert the DIO pins DIO4
and DIO5 to Wire pins.
The -Wire EEPROM interface is only functional when MPU_DIV[2:0] = 000.

UART0 (TX/RX)
The UART0 RX pin should be pulled down by a 10 k
resistor and additionally protected by a 100 pF
ceramic capacitor, as shown in Figure 35.

Optical Interface (UART1)
The OPT_TX and OPT_RX pins can be used for a regular serial interface (by connecting a RS-232
transceiver for example), or they can be used to directly operate optical components (for example, an
infrared diode and phototransistor implementing a FLAG interface). Figure 36 shows the basic connections
for UART1. The OPT_TX pin becomes active when the I/O RAM register OPT_TXE is set to 00.
