16.2.4 READ COMMAND
The READ command instructs the PE to read from
memory the number of 32-bit words specified in the
Operand field starting from the 32-bit address specified
by the Addr_Low and Addr_High fields. This command
can be used to read Flash memory, as well as
Configuration Words. All data returned in response to
this command uses the packed data format that is
shown in Table 16-5.
