Master or slave operation.
Programmable clock bit rate and prescale.
Separate transmit and receive first-in, first-out memory buffers, 16-bits wide, 8 locations
deep.
Programmable choice of interface operation:
–
–
–
Programmable data frame size from 4 to 16-bits.
Independent masking of transmit FIFO, receive FIFO, and receive overrun interrupts.
Internal loopback test mode available.
DMA interface
Compliance to the I
Supports three modes:
–
–
–
Clock synchronization
Master and slave mode configuration possible
Multi-master mode (bus arbitration)
7-bit or 10-bit addressing
7-bit or 10-bit combined format transfers
Slave bulk transfer mode
Ignores CBUS addresses (predessor to I2C that used to share the I2C bus)
Transmit and receive buffers
Interrupt or polled-mode operation
handles bit and byte waiting at all bus speeds
Digital filter for the received SDA and SCL lines
Handles component parameters for configurable software driver support
Supports APB data bus widths of 8, 16 and 32-bits.
