configurations:
•
7- or 8-bit data words, 1 or 2 stop bits, programmable parity (even, odd, or none)
• Programmable baud rates up to 4 Mbps. This is a higher max baud rate relative to the 1.875 MHz,
which is stated by the TIA/EIA-232-F standard.
• 32-byte FIFO on Tx and 32 half-word FIFO on Rx supporting auto-baud

2.10 I2C
The Inter-Integrated Circuit (I2C) provides functionality of a standard I2C master and slave. The I2C is
designed to be compatible with the I2C Bus Specification, version 2.1, by Philips Semiconductor.
I2C provides serial interface for external devices. Data rates of up to 320 kbps are supported.
