P800 Operating Manual
25
For 16-bit wide devices, legal combinations are: 010416 (16
bit gang); 020216 (16 bit 2of2), 040116 (16 bit 1of4),
010232 (32 bit gang).
Set the RAM-START address to the specified hexadecimal
value. Note that this operation is not carried out
immediately, but instead is deferred until after the SE
command is issued - therefore you MUST supply these
commands in the order: SR followed by SE. It is legal to
omit the ram_start parameter if you do not wish to modify it
but intend to use SE.
Set the RAM-STOP address to the specified hexadecimal
value. Note that this command also makes permanent the
RAM-START address specified by a previous SR
command, therefore you MUST supply these commands in
the order SR followed by SE. It is legal to omit the ram_stop
parameter if you do not wish to modify it but intend to use
SR.
Set the DEVICE-START address to the specified
hexadecimal value. Note that this command also sets the
DEVICE-STOP address to:(DEVICE-START + (RAM-range
/ bit-mode-width), so you MUST set the RAM-START, the
RAM-STOP and the bit mode BEFORE using this
command. It is legal to omit the device_start parameter if
you do not wish to modify it but need to modify the device
stop address (having previously modified the RAM range).
Set the destination RAM-START address to the specified
hexadecimal value. This is only used by the BM command,
and should be set before the BM command is executed.
Set the I/O offset to the specified hexadecimal value.
Set the least significant byte (16-bit EPROMs or micros) to
odd or even RAM addresses. The single parameter may be
ASCII 'O' (odd) or 'E' (even).
Set the socket number to which checksum and CRC will
refer.
Set marginal testing to on (1) or off (0).
Set the electronic identifier mode to OFF (0), CHECK (1) or
AUTOMATIC (2).
Set Pre Program checks.
0=No test, 1=Bit check, 2=Empty check.
Read the manufacturer and device code.
This command outputs a six character hexadecimal number
consisting of the Stag manufacturer and device codes for
the currently selected device.
Read the interface format.
This command outputs a single ASCII character
representing the currently selected I/O format, which will
correspond to one of the options available for the S1
command.
