PROCESSOR MODE
The bits 0 of processor mode register 0 as shown in Figure 8 is used
to select which mode of microprocessor mode, and evaluation chip
mode.
Figure 9 shows functions of P00/A0 to P47 pins in each mode.
The external memory area also changes when the mode changes.
Figure 10 shows the memory map for each mode.
The accessing of the external memory is affected by the BYTE pin,
the bit 2 (wait bit) of processor mode register 0, and bit 0 (wait selection
bit) of processor mode register 1.
BYTE pin
When accessing the external memory, the level of the BYTE pin is
used to determine whether to use the data bus as 8-bit width or 16-
bit width.
The data bus width is 8 bits when the level of the BYTE pin is “H”,
and P20/A16/D0 to P27/A23/D7 pins become the data I/O pins.
The data bus width is 16 bits when the level of the BYTE pin is “L”,
and both P20/A16/D0 to P27/A23/D7 pins and P10/A8/D8 to P17/A15/
D15 pins become the data I/O pins.
When accessing the internal memory, the data bus width is always
16 bits regardless of the BYTE pin level.
