• Manufacturer: Freescale Semiconductor / Motorola

TSM Function Parameters Address Maps
HSSR[0:1] - Host Service Request Registers
The Host Service Request Registers control the changes on the pins in states 01 and 10. The TSM function
starts it activity of moving the current position to the desired position when state 11 is written to the two bits
for the respective TSM master channel. After writing a state to the HSSR register, observing the value in
the bits will show a quick return back to state 00.
CPR[0:1] - Channel Priority Registers
The priority for the TSM channels should be coordinated with other functions in the TPU system.
