SPRS581D – JUNE 2009 – REVISED MAY 2012
When initially debugging a device with the password locations in flash programmed (i.e., secured), the
emulator takes some time to take control of the CPU. During this time, the CPU will start running and may
execute an instruction that performs an access to a protected ECSL area. If this happens, the ECSL will
trip and cause the emulator connection to be cut. Two solutions to this problem exist:
1. The first is to use the Wait-In-Reset emulation mode, which will hold the device in reset until the
emulator takes control. The emulator must support this mode for this option.
2. The second option is to use the “Branch to check boot mode” boot option. This will sit in a loop and
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.

INTERRUPTION OF BUSINESS OR OTHER ECONOMIC LOSS.
3.2.11 Peripheral Interrupt Expansion (PIE) Block
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 F28335, 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.
