Fast I2C
Fast I2C supports transfer between components on the same board. The COMe-cVR6 features an onboard I2C
controller connected to the LPC Bus.
The I2C controller supports:
Multimaster transfers
Clock stretching
Collision detection
Interruption on completion of an operation
7.4.
UART
The UART implements an interface for serial communications and supports up to two serial RX/TX ports defined in
the COM Express® specification on pins A98 (SERO_TX) /A99 (SERO_RX) for UART0 and pins A101 (SER1_TX)/A102
(SER1_RX) for UART1. The UART controller is fully 16550A compatible.
Features of the UART are:
On-Chip bit rate ( baud rate) generator
No handshake lines
Interrupt function to the host
FIFO buffer for incoming and outgoing data
