continuously poll the boot mode select pins. The user can select this boot mode and then exit this
mode once the emulator is connected by re-mapping the PC to another address or by changing the
boot mode selection pin to the desired boot mode.
NOTE
When the code-security passwords are programmed, all addresses between
0x33FF80 and 0x33FFF5 cannot be used as program code or data. These locations
must be programmed to 0x0000.
If the code security feature is not used, addresses 0x33FF80 through 0x33FFEF may
be used for code or data. Addresses 0x33FFF0 – 0x33FFF5 are reserved for data and
should not contain program code. .
The 128-bit password (at 0x33 FFF8 – 0x33 FFFF) must not be programmed to zeros.
Doing so would permanently lock the device.

The PIE block serves to multiplex numerous interrupt sources into a smaller set of interrupt inputs. The
PIE block can support up to 96 peripheral interrupts. On the F2833x, 58 of the possible 96 interrupts are
used by peripherals. The 96 interrupts are grouped into blocks of 8 and each group is fed into 1 of 12
CPU interrupt lines (INT1 to INT12). Each of the 96 interrupts is supported by its own vector stored in a
dedicated RAM block that can be overwritten by the user. The vector is automatically fetched by the CPU
on servicing the interrupt. It takes 8 CPU clock cycles to fetch the vector and save critical CPU registers.
Hence the CPU can quickly respond to interrupt events. Prioritization of interrupts is controlled in
hardware and software. Each individual interrupt can be enabled/disabled within the PIE block.
The F2833x supports eight masked external interrupts (XINT1-XINT7, XNMI). XNMI can be connected to
the INT13 or NMI interrupt of the CPU. Each of the interrupts can be selected for negative, positive, or
both negative and positive edge triggering and can also be enabled/disabled (including the XNMI). XINT1,
