Command 09h—Get Utility ROM Version
Command 0Ah—Set Word/Byte Mode Access
The Mode byte should be 0 to set byte access mode or 1 to set word access mode. The current access mode is returned in the sta-
tus flag byte by command 04h, as well as a flag to indicate whether word access mode is supported by this particular bootloader.
Command 0Dh—Get ID Information
For the MAXQ7665/MAXQ7666, the information returned by this command is a zero-terminated ROM banner string.
12.5.2 Family 1 Commands: Load Variable Length (Password Protected)
Command 10h—Load Code Variable Length
This command programs (Length) bytes/words of data into the program flash starting at address (AddressH:AddressL), with the fol-
lowing restrictions.
In byte mode, if the starting address is on an odd word boundary (such as 0001), the low bit will be changed to zero to make it an
even word address.
In byte mode, if an odd number of bytes is input, the data will be padded out with a 00 to make it an even number.
Command 11h—Load Data Variable Length
This command writes (Length) bytes/words of data into the data SRAM starting at address (AddressH:AddressL).
