Commands for DIO RAM (Configuration RAM) and SFR Control:
R
DIO AND SFR CONTROL
Description:
Allows the user to read from and write to DIO RAM and special function registers (SFRs).
Usage:
R [option] [register] … [option]
Command
combinations:
RIx…
Select I/O RAM location x (0x2000 offset is automati-
cally added)
Rx…
Select internal SFR at address x
Rx???...
Read consecutive SFR registers in decimal
Rx$$$...
Read consecutive registers in hex notation
Example:
RI60$$$$
Read all four RTM probe registers
DIO or Configuration RAM space is the address range 0x2000 to 0x20FF. This RAM contains
registers used for configuring basic hardware and functional properties of the 71M6521 and is
organized in bytes (8 bits). The 0x2000 offset is automatically added when the command RI is
typed. The SFRs (special function registers) are located in internal RAM of the 80515 core,
starting at address 0x80.
Commands for EEPROM Control:
EE
EEPROM CONTROL
Description:
Allows user to enable read and write to EEPROM.
Usage:
EE [option] [arguments]
Command
combinations:
EECn
EEPROM Access (1
Enable, 0
Disable)
EERa.b
Read EEPROM at address 'a' for 'b' bytes.
EEE
Erase the EEPROM
EESabc..xyz
Write characters to buffer (sets Write length)
EETa
Transmit buffer to EEPROM at address 'a'.
EEWa.b...z
Write values to buffer
Example:
EEShello; EET$0210
Writes 'hello' starting at EEPROM address 0x210.
The EEC1 command must be issued before the EEPROM interface can be used. The execution of the EEE
command takes several seconds. During this time, no other commands can be entered.
Auxiliary Commands:
AUXILIARY
Description:
Various
Commands:
,
Typing a comma (“,”) repeats the command issued
from the previous command line. This is very helpful
when examining the value at a certain address over
time, such as the CE DRAM address for the
temperature.
/
The slash (“/”) is useful to separate comments from
commands when sending macro text files via the serial
interface. All characters in a line after the slash are
ignored.
BT
Commands execution of a battery test.
