Interface Specification
Both UART (asynchronous) and I/O Interface (synchronous) modes are supported. The communication
formats are shown below. In the subsections that follow, virtual addresses are indicated, unless
otherwise noted.
Data Transfer Format
The host controller is to issue one of the commands listed in Table 3.2
should occur in response to each command.
to the target board. Table 3.3 to Table 3.5 illustrate the sequence of two-way communications that
In Single Boot mode, an SIO channel is used for communications with a programming controller.
