Command 16 Temp Basal

The 0x16 command is a follow-on command for the Command 0x1A Table 1 case to set a fixed or percentage temporary basal rate.

16 LL SS 00 AAAA BBBBBBBB AAAA BBBBBBBB CCCC 

• LL (1 byte): Length of command.
• SS (1 byte): Unknown. 3c or 7c.
• AAAA (2 bytes): Total insulin to deliver for complete period. Example: 1.10U/H for 1.5 hours = 1.10*3*100 = 330 = 0x014a
• BBBBBBBB (4 bytes): Delay between pulses, expressed in counts of a 100kHz timer. Example: 3.0U/hr = 60 pulses per hour = 60s between pulses = 6000000 counts = 0x5b8d80
• CCCC (2 bytes): Checksum?

Temp basal subcommand 0x16 looks quite consistent with a numbering, corresponding with for what is seems the hours and a specific following byte c, 18, a4, 30, 48

The 16 command's data is 8 bytes followed by 6-byte chunks (just one chunk in this case). Each chunk is a word followed by a dword. In this case $0bb8 (= decimal 3000) followed by $000927c0 (decimal 600000). Note the nice round decimal values in the command. I've found the code that parses the chunks and puts them into tables Tab9 and Tab11 (presumably for processing elsewhere).

It could be the time when the beep sounds when the temp basal is done?
