read and write signals (P3.6 - WR# and P3.7 - RD#) for
external memory use. Table 3-1 shows external data mem-
ory RD#, WR# operation with EXTRAM bit.
The stack pointer (SP) can be located anywhere within the
256 bytes of internal RAM (lower 128 bytes and upper 128
bytes). The stack pointer may not be located in any part of
the expanded RAM.
