7.16 VPB1 bridge
This section describes the interfaces and function of the VPB1 bridge. The VPB1 bridge
acts as a bridge between the UART and the EPICS7B DIO interface. Two bridges are
used; one to connect to several slow blocks and an additional one specifically for the
universal synchronous receiver transmitter, which is commonly used to implement a serial
interface. In any case where a device needs a low overhead, standard, low performance
interface, a UART can be used. The UART includes advanced features like a fractional
clock divider.
7.17 UART configuration
The UART interface is used to be implemented as a serial interface to, for example a
modem and is compatible with the industry standards 16650 UARTs.
No full modem interface is included, only the CTS and RTS modem signals are available.
The UART interface can also be configured as an IrDA (InfraRed Digital Association) SIR
(Serial InfraRed) interface, which has a pulse and polarity compliancy with the IrDA
Version 1.0 Physical Layer Specification.
