cardGet
cardGet — gives
read access to card buffers for low-level
debugging.
Synopsis
(cardGet card_id page offset nbytes)
Parameters
- card_id
- The card ID associated with the
card initialized by this command.
- page
The
page of card memory to access. The card contains 256 Kbytes
of memory, mapped into the card buffer as 16Kbyte
pages. Pages are numbered from 0 to
15. The Pfbprofi
software module utilizes specific pages for its various
functions, such as control structures, I/O data, DP Master
control blocks, etc. To facilitate access, the page
parameters can also be specified by name, as follows:
- offset
- The starting byte offset into the card buffer,
as a decimal or hex (0xnnnn) number.
- nbytes
- The
number of bytes to be transmitted.
Returns
The list of bytes read, in ASCII BCD, formatted as:
(cardGet card_id card offset nbytes byte0 byte1 ... byteN)
otherwise (error).
Description
This command provides direct read access to the hardware card
buffers (if available). It is intended for use only during very
low-level debug.
