Table 13-31 lists the memory-mapped registers for the RTDMA_MPU_REGS registers. All register offset addresses not listed in Table 13-31 should be considered as reserved locations and the register contents should not be modified.

Complex bit access types are encoded to fit into small table cells. Table 13-32 shows the codes that are used for access types in this section.
Access Type | Code | Description |
---|---|---|
Read Type | ||
R | R | Read |
Write Type | ||
W | W | Write |
W1S | W 1S | Write 1 to set |
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. |
MPUR_CHMASK is shown in Figure 13-29 and described in Table 13-33.
