DSCR[5:0] are TPU breakpoint enables. Setting a bit enables a breakpoint condition.
BP — Break if mPC equals mPC breakpoint register.
BC — Break if CHAN register equals channel breakpoint register at beginning of state
BH — Break if host service latch is asserted at beginning of state.
BL — Break if link service latch is asserted at beginning of state.
BM — Break if MRL is asserted at beginning of state.
BT — Break if TDL is asserted at beginning of state.
If an internal breakpoint caused the TPU to enter the halted state, the TPU asserts the
BKPT signal on the IMB and the BKPT flag. The TPU continues to assert BKPT until
it recognizes a breakpoint acknowledge cycle from a host, or until the FREEZE signal
on the IMB is asserted.
PCBK is asserted if a breakpoint occurs because of a PC register match with the PC
breakpoint register. PCBK is negated when the BKPT flag is negated.
CHBK is asserted if a breakpoint occurs because of a CHAN register match with the
channel register breakpoint register. CHBK is negated when the BKPT flag is negated.
SRBK is asserted if a breakpoint occurs because of any of the service request latches
being asserted along with their corresponding enable flag in the development support
control register. SRBK is negated when the BKPT flag is negated.
TPUF is asserted whenever the TPU is in a halted state as a result of FREEZE being
asserted. This flag is automatically negated when the TPU exits the halted state be-
cause of FREEZE being negated.
