] CE Data Access
Description: Allows user to read from and write to CE data space.
Usage: ] {Starting CE Data Address}{option}…{option}<CR>
Command
Combinations:
]saddr?<CR> Read 32-bit word in decimal.
]saddr??<CR> Read two consecutive 32-bit words in decimal.
]saddr???<CR> Read three consecutive 32-bit words in decimal.
]saddr$<CR> Read 32-bit words in hex.
]saddr$$<CR> Read two consecutive 32-bit words in hex.
]saddr$$$<CR> Read three consecutive 32-bit words in hex.
]U<CR> Update default version of CE Data in
FLASH. Important: The CE must be
stopped (CE0) before issuing this
command! Also, remember to restart
by executing the CE1 command prior to
attempting measurements.
Examples: ]40$<CR> Reads CE data word 0x40 in hex.
]40$$<CR> Reads CE data words 0x40 and 0x41 in hex.
]40$$$<CR> Reads CE data words 0x40, 0x41 and 0x42 in
hex.
]40?<CR> Reads CE data words 0x40 in decimal.
]40??<CR> Reads CE data words 0x40 and 0x41 in decimal.
]40???<CR> Reads CE data words 0x40, 0x41 and 0x42 in
decimal.
]7E=12345678<CR> Writes word at 0x7E (hex format).
]7E=12345678=9876ABCD<CR> Writes two words starting at 0x7E (hex format).
]7E=+2255<CR> Write the value 2255 in decimal to location 0x7E.
]7E=+2255=+456<CR> Write the value 2255 in decimal to location 0x7E
and the value 456 in decimal to location 0x7F.
CE data space is the address range for the CE DRAM (0x1000 to 0x13FF). All CE data words
are in 4-byte (32-bit) format. The offset of 0x1000 does not have to be entered when using the
] command, thus typing ]A? will access the 32-bit word located at the byte address 0x1000 + 4
* A = 0x1028.
