When the current 16-bit address (code or xdata) matches the BPADDRH/BPADDRL
address, a breakpoint event occurs. The BPPULSE and BPEN bits in the USBBAV regis-
ter control the action taken on a breakpoint event.
If the BPEN bit is “0,” address breakpoints are ignored. If BPEN is “1” and BPPULSE is
“1,” an 8 CLK24 wide pulse appears on the BKPT pin. If BPEN is “1” and BPPULSE is
“0,” the BKPT pin remains active until the 8051 clears the BREAK bit by writing “1” to it.
