Complex bit access types are encoded to fit into small table cells. Table 3-233 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 |
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. |
B0_Z2_LINKPOINTER is shown in Figure 3-212 and described in Table 3-234.
