RESET:
The FRZ bits specify the TPU microengine response to the IMB FREEZE signal. Refer
to Table D-57.
CCL controls the latching of channel conditions (MRL and TDL) when the CHAN reg-
ister is written.
These bits are TPU2 breakpoint enables. Setting a bit enables a breakpoint condition.
Table D-58 shows the different breakpoint enable bits.
If an internal breakpoint caused the TPU2 to enter the halted state, the TPU2 asserts
the BKPT signal on the IMB and sets the BKPT flag. BKPT remains set until the TPU2
recognizes a breakpoint acknowledge cycle, or until the IMB FREEZE signal is
asserted.
0 = Only the pin state condition of the new channel is latched as a result of the write
1 = Pin state, MRL, and TDL conditions of the new channel are latched as a result
