I2C MASTER

The I2C Master enables control of I2C slave devices,

including support for clock stretching slaves. I2C Multi-

master and bus arbitration protocols are not supported.

For implementation details refer to the On-Chip Software

Development Kit (On-Chip SDK).

SPI MASTER

TheEternaSPImastercontrollersupportsallconfigurations

ofclockpolarityandphase,supportingshiftclockfrequen-

cies of 460.8kHz, 921.6kHz, 1.8432MHz, or 3.6864MHz.

In addition the SPI master controller can be configured to

repetitively issue commands and capture the correspond-

ing output, enabling repetitive sampling of signals from a

SPI ADC or SPI sensor based upon a clock reference of

better than ±50ppm. For implementation details refer to

the On-Chip Software Development Kit (On-Chip SDK).

1-WIRE MASTER

The Eterna 1-Wire Master controller supports the reset,

presencedetect,readandwrite1-Wireprotocoloperations,

incorporatinganactivepull-up. Theactivepull-upbecomes

active when the passive pull-up raises the voltage on the

1_WIRE pin nominally above 1.4V, driving the 1_WIRE

signal as specified in Digital I/O Characteristics. For

implementation details refer to the On-Chip Software

Development Kit (On-Chip SDK).
