Table 18-31 lists the memory-mapped registers for the DLT_FIFO_REGS registers. All register offset addresses not listed in Table 18-31 should be considered as reserved locations and the register contents should not be modified.
| Offset | Acronym | Register Name | Protection |
|---|---|---|---|
| 0h | FIFO_BUF_L | FIFO Content Register | |
| 4h | FIFO_BUF_H | FIFO Content Register | |
| 1000h + formula | FIFO_MEM_y | FIFO access in Memory mode |
Complex bit access types are encoded to fit into small table cells. Table 18-32 shows the codes that are used for access types in this section.
| Access Type | Code | Description |
|---|---|---|
| Read Type | ||
| R | R | Read |
| 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. | |
FIFO_BUF_L is shown in Figure 18-22 and described in Table 18-33.
