MCF8316C-Q1: Motor Not Spinning - Can Hear Clicking Sound

Tool/software:

Hello - I am trying to simply spin a motor with the MCF8316C-Q1. I have all the EEPROM registers set to the default values from Table 8-3 in the spec sheet. I have no problem reading and writing to registers.

My understanding is I can set the speed via I2C by using register 0xEC. I started by writing 0x00001000 then 0x00002000 then 0x00003FFF assuming that means 12.5%, 25%, and 50% respectively. The motor does not move, but I do hear it clicking. The motor works with other ESCs / motor controllers.

I assume I am writing to the register incorrectly or that I am writing to the wrong register. Any help is appreciated.

EDIT: After unplugging the system and plugging it back in, I don't hear the motor clicking.
