ASC Interface
Universal Access Device 2+ provides a buffered asynchronous communication path between an
external RS232 device controlled by the target system application and the ASC0 of the target
system controller.
In ASC-BSL/CAN, ASC-BSL/3Pin or ASC-BSL/SSC mode, after booting up the target system
controller via ASC0 and transferring the monitor code the ASC0 channel will no longer be used by
the debug communication and is therefore available for the application. With the buffered ASC0 of
Universal Access Device 2+, the application's external RS232 device does not need to be manually
reconnected - this is automatically done by Universal Access Device 2+.
Additionally to the buffered ASC0 via RS232, an unbuffered TTL-level ASC0 is available. For this,
no additional hardware (RS232 driver) at the target system is required - the signal lines TxD and
RxD are directly connected to the corresponding controller pins.
SSC Interface
As no additional hardware is required, the maximum transmission speed of up to 5Mbps can be
achieved.
