In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode, these pins become data I/O pins and
operate as follows:
(1) When using 16-bit width as external data bus width:
(2) When using 8-bit width as external data bus width:

external memory area access cycle.
The value is input into high-order internal data bus (DB
