Bitrate Values[edit]

Value Converted divisor value Bits-per-second / description
3 10 115200
4 12 96000
5 16 72000
6 24 48000 (This is the default for IRU)
7 32 36000
8 48 24000
9 64 18000
10 96 12000
11 120 9600
12 192 6000
13 384 3000
14 20 57600
15 30 38400
16 60 19200
17 160 7200
18 240 4800

The bps listed above is from code in IR module which converts the input value into actual bps, that function is only used with delay code however.

The converted value is the following(from a datasheet): "16-bit divisor for generation of the baud clock in the baud rate generator". The baud/bit rate is calculated with the following, where clk is 1152000: bitrate = clk / divisor.

Description[edit]

This sets the current bitrate. Error 0xE0E10FED is returned when the input value is outside of the above range. Error 0xF9610C02 is returned when the I2C code returns an error.
