11.2 Reserved Symbols
The symbols defined by the µPD17225 device file are listed in Table 11-2.
The defined symbols are the following register file names, port names, and peripheral hardware names.
11.2.1 Register file
The names of the symbols assigned to the register file are defined. These registers are accessed by the PEEK
and POKE instructions through the window register (WR). Figure 11-1 shows the register file.
11.2.2 Registers and ports on data memory
The names of the registers assigned at addresses 00H through 7FH on the data memory and the names of ports
assigned to address 70H and those that follow, and system register names are defined. Figure 11-2 shows the data
memory configuration.
11.2.3 Peripheral hardware
The names of peripheral hardware accessed by the GET and PUT instructions are defined. Table 11-3 shows
the peripheral hardware.
