Table 25-51 lists the memory-mapped registers for the EMIF1_CONFIG_REGS registers. All register offset addresses not listed in Table 25-51 should be considered as reserved locations and the register contents should not be modified.
Offset | Acronym | Register Name | Write Protection | Section |
---|---|---|---|---|
0h | EMIF1LOCK | EMIF1 Config Lock Register | EALLOW | Go |
2h | EMIF1COMMIT | EMIF1 Config Lock Commit Register | EALLOW | Go |
4h | EMIF1MSEL | EMIF1 Master Sel Register | EALLOW | Go |
8h | EMIF1ACCPROT0 | EMIF1 Config Register 0 | EALLOW | Go |
Complex bit access types are encoded to fit into small table cells. Table 25-52 shows the codes that are used for access types in this section.
Access Type | Code | Description |
---|---|---|
Read Type | ||
R | R | Read |
R-0 | R -0 | Read Returns 0s |
Write Type | ||
W | W | Write |
WSonce | W Sonce | Write Set once |
Reset or Default Value | ||
-n | Value after reset or the default value | |
Register Array Variables | ||
i,j,k,l,m,n | When these variables are used in a register name, an offset, or an address, they refer to the value of a register array where the register is part of a group of repeating registers. The register groups form a hierarchical structure and the array is represented with a formula. | |
y | When this variable is used in a register name, an offset, or an address it refers to the value of a register array. |
EMIF1LOCK is shown in Figure 25-38 and described in Table 25-53.
