HMC6343
Timing
Upon power application to the HMC6343, wait nominally 500 milli-seconds before sending the first I2C command (typically
a 0x32 byte followed by a 0x50 byte for the usual heading/pitch/roll). Depending on the command sent, a delay time
should be inserted before clocking out the response bytes (send 0x33, clock back response bytes). The following table
indicates the response delay times for various commands.
