C Commands to Flash the Application Algorithm/Firmware
The MAX32664 is pre-programmed with bootloader firmware which accepts in-application programming
of the Maxim supplied application algorithm/firmware file (.msbl). Table 121 is a capture of the I

C
commands that are necessary to flash the application algorithm/firmware to the MAX32664.
IMPORTANT: Do not enable the accelerometer if your board does not have the accelerometer.
This example was captured with the MAX32630FTHR acting as the host microcontroller. The MAX32664
uses the 8-bit slave address of 0xAA. The example encrypted algorithm file used was the
MAX32660_SmartSensor_OS24_MaximFast_1.8.2a.msbl (26 pages, 8196 bytes for the page size). Each
