AN2364 Freescale Semiconductor / Motorola, AN2364 Datasheet - Page 12

• Manufacturer Part Number: AN2364
• Description: Using the Table Stepper Motor TPU Function (TSM) with the MPC500 Family
• Manufacturer: Freescale Semiconductor / Motorola

TSM Function Parameters Address Maps
CIER - Channel Interrupt Enable Register
CFSR[0:3] - Channel Function Select Registers
CFS[3:0] -- Function Number (Assigned during microcode assembly).
HSQR[0:1] - Host Sequence Registers
When initializing the Host Sequence Register bits, a logical “OR” of the two bits per channel should be used
in code. The initialization function in the TSM API interface performs this activity.
