Figure 24. PMBUS Address Detection Method

PMBus/I2C address 0x7E is a reserved address and should not be used in a system using the UCD3138x. This

address is used for manufacturing test.

9.3.6.3 SPI

The SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of programmed length

(1 to 16 bits) to be shifted into and out of the device at a programmed bit-transfer rate. The SPI is normally used

for communication between the UCD3138x and external peripherals. Typical applications include an interface to

external I/O or peripheral expansion via devices such as shift registers, display drivers, SPI EPROMs and

analog-to-digital converters. The SPI allows serial communication with other SPI devices through a 3-pin or 4-pin

mode interface. The SPI typically is configured as a master for communicating to external EEPROM.
