Peripheral Frame 2 only allows 16-bit accesses. All 32-bit accesses are ignored (invalid data may be returned or written).
Missing segments of memory space are reserved and should not be used in applications.
These registers are used to control the protection mode of the C28x CPU and to monitor some critical
device signals. The registers are defined in
Table 3-11

The first byte (00) denotes flash devices. FF denotes ROM devices. Other values are reserved for future devices.
Figure 3-7
shows how the various interrupt sources are multiplexed within the 280x devices.
Eight PIE block interrupts are grouped into one CPU interrupt. In total, 12 CPU interrupt groups, with 8
interrupts per group equals 96 possible interrupts. On the 280x, 43 of these are used by peripherals as
shown in
Table 3-12
.
The TRAP #VectorNumber instruction transfers program control to the interrupt service routine
corresponding to the vector specified. TRAP #0 attempts to transfer program control to the address
pointed to by the reset vector. The PIE vector table does not, however, include a reset vector. Therefore,
TRAP #0 should not be used when the PIE is enabled. Doing so will result in undefined behavior.
