2.4 Single-chip Mode
Figure 2.4.1 Processor mode register 0
Figure 2.4.2 Processor mode register 1
This microcomputer supports single-chip mode only.
In single-chip mode, only internal memory space (SFR, OSD RAM, internal RAM, and internal ROM) can
be accessed. Ports P0, P2 to P10 can be used as programmable I/O ports or as I/O ports for the internal
peripheral functions.
Figure 2.4.1 shows the processor mode register 0 and Figure 2.4.2 shows the processor mode register 1.
Figure 2.4.3 shows the memory map.
