Legend: R = Read; R/W = Read/Write; ‘x’ in a register name = 0-13; y’ in a register name = 0-8.
Note 1: Reset values for these bits are ‘0’, ‘1’, ‘1’, ‘1’, respectively.
2: The BASE<21:0> bits must be set to the corresponding Physical Address and right shifted by 10 bits. For Read-only bits, this value is set by hardware on Reset.
3: The SIZE<4:0> bits must be set to the corresponding Region Size, based on the following formula: Region Size = 2
(SIZE-1)
x 1024 bytes. For read-only bits, this value is set by hardware on Reset.
4: Refer to the Device Memory Maps (Figure 4-1 through Figure 4-4) for specific device memory sizes and start addresses.
5: See Table 4-1for information on specific target memory size and start addresses.
6: The SBTxREG1 SFRs are reserved, and therefore, are not listed in this table for this target.
