3.3 Register Map
The F281x and C281x devices contain three peripheral register spaces. The spaces are categorized as
follows:
Peripheral Frame 0: These are peripherals that are mapped directly to the CPU memory bus.
See Table 3-6.
Peripheral Frame 1: These are peripherals that are mapped to the 32-bit peripheral bus.
See Table 3-7.
Peripheral Frame 2: These are peripherals that are mapped to the 16-bit peripheral bus.
See Table 3-8.
Table 3-6. Peripheral Frame 0 Registers

NAME ADDRESS RANGE SIZE (x16) ACCESS TYPE
(2)
Device Emulation Registers 0x00 0880 – 0x00 09FF 384 EALLOW protected

XINTF Registers 0x00 0B20 – 0x00 0B3F 32 Not EALLOW protected
Reserved 0x00 0B40 – 0x00 0BFF 192
CPU-TIMER0/1/2 Registers 0x00 0C00 – 0x00 0C3F 64 Not EALLOW protected
Reserved 0x00 0C40 – 0x00 0CDF 160
PIE Registers 0x00 0CE0 – 0x00 0CFF 32 Not EALLOW protected
PIE Vector Table 0x00 0D00 – 0x00 0DFF 256 EALLOW protected
Reserved 0x00 0E00 – 0x00 0FFF 512
(1) Registers in Frame 0 support 16-bit and 32-bit accesses.
(2) If registers are EALLOW protected, then writes cannot be performed until the user executes the EALLOW instruction. The EDIS
instruction disables writes. This prevents stray code or pointers from corrupting register contents.
(3) The Flash Registers are also protected by the Code Security Module (CSM).
Table 3-7. Peripheral Frame 1 Registers
(1)
NAME ADDRESS RANGE SIZE (x16) ACCESS TYPE
256 Some eCAN control registers (and selected bits in
eCAN Registers 0x00 6000 – 0x00 60FF
(128 x 32) other eCAN control registers) are EALLOW-protected.
256
eCAN Mailbox RAM 0x00 6100 – 0x00 61FF Not EALLOW-protected
(128 x 32)
Reserved 0x00 6200 – 0x00 6FFF 3584
(1) The eCAN control registers only support 32-bit read/write operations. All 32-bit accesses are aligned to even address boundaries.
