P800 Operating Manual
11
In the case of 16-bit wide devices all 8 sockets will program with the same data. Two bytes
of RAM are required for each device word, and the order in which these are stored is (by
default) high byte first, low byte last. This default may be modified by the user (see section
2.3
above). Loading is done from socket 1.
2.3.5 16-bit 2of2 (2 sets of 2 parts)
This mode is available for 16 bit wide parts only.
In 2of2 set mode data in the RAM is stored in two blocks, one block for sockets 1 and 3,
followed by one block for sockets 2 and 4. The block size is the size of the device selected.
- Sockets 1 and 3 will program/verify with data starting at RAM START.
- Sockets 2 and4 will program/verify with data starting at (RAM START + device size).
Loading will over write any existing data in the RAM for all sockets. Devices are required in
sockets 1 and 2.
2.3.6 16-bit 1of4 (1 set of 4 parts)
For 8-bit wide devices data in the RAM is stored in two blocks, one block for the socket pair
1 and 2, with the second block for the socket pair 3 and 4. The block size is twice the size of
the device selected.
- Socket 1 will program/verify with data starting at RAM START.
- Socket 2 will program/verify with data starting at (RAM START + 1).
- Socket 3 will program/verify with data starting at (RAM START + (device size x 2)).
- Socket 4 will program/verify with data starting at (RAM START + (device size x 2) +1).
Loading requires 4 devices, one in all 4 sockets.
For 16 bit parts data in the RAM is stored in four blocks, one block for each socket. The
block size is the size of the device selected.
- Socket 1 will program/verify with data starting at RAM START.
- Socket 2 will program/verify with data starting at (RAM START + device size).
- Socket 3 will program/verify with data starting at (RAM START + (device size x 2)).
- Socket 4 will program/verify with data starting at (RAM START + (device size x 3)).
Loading will over write any existing data in the RAM for all sockets. 3 or 4 devices may be
present, as long as there are devices in sockets 1, 2 and 3.
2.3.7 32-bit Gang
In 32 BIT GANG mode, groups of 32 bit data may be programmed.
For an 8-bit wide device the mapping will be as follows:
Socket
1
2
3
Image
A
B
C
The data for image A will be stored at addresses ending 0, 4, 8 and C (hex) the data for
image B will be stored at addresses ending 1, 5, 9 and D (hex), the data for image C will be
4
D
