DSCLK, the gated serial clock, is normally high, but it pulses low for each bit to be
transferred. At the end of the seventeenth clock period, it remains high until the start of the
next transmission. Clock frequency is implementation dependent and may range from DC
to the maximum specified frequency. Although performance considerations might dictate a
hardware implementation, software solutions can be used provided serial bus timing is
maintained.
5.6.2.8 COMMAND SET. The following paragraphs describe the command set available in
BDM.
5.6.2.8.1 Command Format. The following standard bit format is utilized by all BDM
commands.

R/W Field
Operand Size
Address/Data (A/D) Field

The operation field specifies the commands. This 6-bit field provides for a maximum of
64 unique commands.
The R/W field specifies the direction of operand transfer. When the bit is set, the
transfer is from CPU to development system. When the bit is cleared, data is written to
the CPU or to memory from the development system.
For sized operations, this field specifies the operand data size. All addresses are
expressed as 32-bit absolute values. The size field is encoded as listed in Table 5-22.
The A/D field is used by commands that operate on address and data registers. It
determines whether the register field specifies a data or address register. One indicates
an address register; zero indicates a data register. For other commands, this field may
be interpreted differently.
