Configuration Order
MOTOROLA DC Motor with Dead-Time Correction – XOR version TPU Function Set (DCmDtXor)
NOTE:
The CPU configures the TPU as follows.
A CPU routine that configures the TPU can be generated automatically using
the MPC500_Quick_Start Graphical Configuration Tool.
1. Disables the channels by clearing the two channel priority bits on each
2. Selects the channel functions on all used channels by writing the
3. Initializes function parameters. The parameters T, DT and
4. Issues an HSR (Host Service Request) type %10 to one of the
5. Enables servicing by assigning high, middle or low priority to the channel

sync_presc_addr must be set before initialization. If a DCmDtXor_sync
channel or a DCmDtXor_res channel is used, then its parameters must
also be set before initialization.

priority bits. All DCmDtXor_C and DCmDtXor_T channels must be
assigned the same priority to ensure correct operation. The CPU must
ensure that the DCmDtXor_sync or DCmDtXor_res function is initialized
after the initialization of DCmDtXor:

–
assign a priority to the DCmDtXor_C and DCmDtXor_T channels to
enable their initialization
if a Synchronization Signal or a Resolver Reference Signal channel
is used, wait until the HSR bits are cleared to indicate that
initialization of the DCmDtXor_C and DCmDtXor_T channels has
completed and
assign a priority to the DCmDtXor_sync or DCmDtXor_res channel
to enable its initialization
