PCBK is asserted if a breakpoint occurs because of a PC (microprogram counter)
register match with the PC breakpoint register. PCBK is negated when the BKPT flag
is cleared.
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 TPU2 is in a halted state as a result of FREEZE being as-
serted. This flag is automatically negated when the TPU2 exits the halted state be-
cause 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 TPU2 is assigned 16 unique interrupt vector numbers, one vector number for each
channel. The CIBV field specifies the most significant nibble of all 16 TPU2 channel
interrupt vector numbers. The lower nibble of the TPU2 interrupt vector number is de-
termined by the channel number on which the interrupt occurs.
