To simplify the description of programming details, all
operations will be described using pseudo operations.
There are several functions used in the pseudocode
descriptions. These are used either to make the
pseudocode more readable, to abstract implementa-
tion-specific behavior, or both. When passing parame-
ters with pseudo operation, the following syntax will be
used: 5’h0x03 (i.e., send 5-bit hex value 0x03). These
functions are defined in this section, and include the
following operations:
• SetMode (mode)
• SendCommand (command)
• oData = XferData (iData)
• oData = XferFastData (iData)
• oData = XferInstruction (instruction)

SetMode (mode)
To set the EJTAG state machine to a specific state.
The value of mode is clocked into the device on
signal TMS. TDI is set to a ‘0’ and TDO is ignored.
