When the DC bits in the data breakpoint control register
are not set to ‘0’, data breakpoints are activated. When
the value of the DC bits is ‘1’ or ‘3’, any data address from
load operations (if the BL bit is set) and/or store opera-
tions (if the BS bit is set) issued by the DSPCPU is com-
pared against the low and high address-range values.
The DAC bit in the breakpoint control register determines
whether data addresses need to be inside or outside of
the range defined by the low and high address-range
registers. A successful comparison occurs when either:
• DAC = ‘0’ and low ≤ daddr ≤ high, or
• DAC = ‘1’ and daddr < low or daddr > high.
