¡ Semiconductor
The MSM7630 uses only 6 interrupts of the 16 interrupt levels.
2.2.5 BPA: Breakpoint Address (read/write)
This read/write register sets and shows the instruction address (byte address) where a breakpoint
trap occurred. The lowest 2 bits will always be "0". When EBP of %PSR is "1", a trap will be generated
immediately before execution of the instruction at the breakpoint set by this register. This register
will be undefined after reset.
2.2.6 PC: Program Counter (read-only)
This read-only register provides the instruction address (byte address) in the execution phase. Its
lowest 2 bits will always be "0".
2.2.7 nPC: Next Program Counter (read-only)
This read-only register provides the instruction address (byte address) in the instruction decode
phase. Its lowest 2 bits will always be "0".
