CHBK is asserted if a breakpoint occurs because of a CHAN register match with the
CHAN register breakpoint register. CHBK is negated when the BKPT flag is cleared.
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 cleared.
TPUF is set whenever the TPU is in a halted state as a result of FREEZE being as-
serted. This flag is automatically negated when the TPU exits the halted state because
of FREEZE being negated.
This three-bit field specifies the interrupt request level for all channels. Level seven for
this field indicates a non-maskable interrupt; level zero indicates that all channel inter-
rupts are disabled.
The TPU is assigned 16 unique interrupt vector numbers, one vector number for each
channel. The CIBV field specifies the most significant nibble of all 16 TPU channel in-
terrupt vector numbers. The lower nibble of the TPU interrupt vector number is deter-
mined by the channel number on which the interrupt occurs.
