The following dedicated and multi-use pins can be assigned as LCD segments:
15 dedicated LCD segment pins: SEG0 to SEG2, SEG8, SEG12 to SEG18, SEG20 to SEG23.
9 dual-function pins: MUX_SYNC/SEG7, CKTEST/SEG19, E_RXTX/SEG9, E_TCLK/SEG10,
E_RST/SEG11, SEG3/PCLK, SEG4/PSDO, SEG5/PCSZ, SEG6/PSDI.
5 additional dual-function pins in the 71M6534: SEG51/E_TBUS0, SEG52/E_TBUS1,
SEG53/E_TBUS2, SEG54/E_TBUS3, SEG55/E_ISYNC
33 (71M6533) or 46 (71M6534) combined DIO and segment pins
o
71M6533: SEG24/DIO4 to SEG31/DIO11, SEG33/DIO13 to SEG41/DIO21, SEG43/DIO23 to
SEG47/DIO27, SEG49/DIO29, SEG50/DIO30, SEG61/DIO41, SEG63/DIO43 to
SEG65/DIO45, and SEG67/DIO47 to SEG71/DIO51.
o
71M6534: SEG24/DIO4 to SEG50/DIO30, SEG56/DIO36 to SEG59/DIO39, SEG61/DIO41 to
SEG75/DIO55.

Connecting I
2C EEPROMs
I
2C EEPROMs or other I2C compatible devices should be connected to the DIO pins DIO4 and DIO5, as
shown in Figure 34.
Pull-up resistors of roughly 10 k
to V3P3D (to ensure operation in BROWNOUT mode) should be used
for both SCL and SDA signals. The DIO_EEX register in I/O RAM must be set to 01 in order to convert
the DIO pins DIO4 and DIO5 to I
2C pins SCL and SDA.
