Commands for I/O RAM (Configuration RAM) and SFR Control:
R I/O RAM AND SFR CONTROL Comment
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 automatically
added)
Rx… Select internal SFR at address x
Ra???... Read consecutive SFR registers in Decimal, starting at ad-
dress a
Ra$$$... Read consecutive registers in Hex, starting at address a
Ra=n=m… Set values of consecutive registers to n and m starting at
address a
Example: RI2$$$ Read DIO RAM registers 2, 3, and 4 in Hex.
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 Comment
Description: Allows user to enable read from 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.
EESabc..xyz Write characters to buffer (sets Write length)
EETa Transmit buffer to EEPROM at address 'a'.
EEWa.b...z Write values to buffer
CLS Saves calibration to EEPROM
Example: EEShello
EET$0210 Writes 'hello' to buffer, then transmits buffer to EEPROM start-
ing at address 0x210.
Due to buffer size restrictions, the maximum number of bytes handled by the EEPROM command is 0x40.
Commands for Flash Memory Control:
F FLASH CONTROL Comment
Description: Allows user to enable read from and write to Flash memory.
Usage: F [option] [arguments]
Command
combinations:
FRa.b Read Flash at address 'a' for 'b' bytes.
FSabc..xyz Write characters to buffer (sets Write length)
FTa Transmit buffer to Flash memory at address 'a'.
FWa.b...z Write string of bytes to buffer
Example: FShello
FT$FE10 Writes 'hello' to buffer, then transmits buffer to EEPROM start-
ing at address 0xFE10.
