DESCRIPTION
These pins can be left floating.
DESCRIPTION
EEPROM Chip Select: SR_CS is an output signal with a weak
internal pull-up resistor.
EEPROM Data Input: Serial data input interface to the EEPROM.
SR_DI is an input signal with a weak internal pull-up resistor.
EEPROM Data Output: Serial data output interface to the
EEPROM. SR_DO is an output signal with a weak internal pull-up
resistor.
EEPROM Clock Output.
DESCRIPTION
1.8 V Power Pin: Used as digital core power pins.
1.8 V Power Pin: Used as analog core power pins.
3.3 V Power Pin: Used as digital I/O power pins.
1.8 V Power Pin: Used as auxiliary power pins.
1.8V Termination Voltage: Provides driver termination voltage at
transmitter. Should be given the same consideration as VDDCAUX.
Ground Pin: Used as ground pins.
