P89V660/662/664
80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
for the 89V662, above 6FFH for the 89V664) will access external off-chip memory and will
perform in the same way as the standard 8051, with P0 and P2 as data/address bus, and
P3[6] and P3[7] as write and read timing signals.
When EXTRAM = 0, MOVX @Ri and MOVX @DPTR will be similar to the standard 8051.
Using MOVX @Ri provides an 8-bit address with multiplexed data on Port 0. Other output
port pins can be used to output higher order address bits. This provides external paging
capabilities. Using MOVX @DPTR generates a 16-bit address. This allows external
addressing up the 64 kB. Port 2 provides the high-order eight address bits (DPH), and
Port 0 multiplexes the low order eight address bits (DPL) with data. Both MOVX @Ri and
MOVX @DPTR generates the necessary read and write signals (P3[6] - WR and P3[7] -
RD) for external memory use. Table 7 shows external data memory RD, WR operation
with EXTRAM bit.
The stack pointer (SP) can be located anywhere within the 256 B of internal RAM (lower
128 B and upper 128 B). The stack pointer may not be located in any part of the expanded
RAM.

EXTRAM
Internal/External RAM access using MOVX @Ri/@DPTR. When ‘1’,
accesses internal XRAM with address specified in MOVX instruction.
If address supplied with this instruction exceeds on-chip available
XRAM, off-chip RAM is accessed. When ‘0’, every MOVX instructions
targets external data memory by default.
0
AO
ALE off: disables/enables ALE. AO = 0 results in ALE emitted at a
constant rate of 12 the oscillator frequency. In case of AO = 1, ALE is
active only during a MOVX or MOVC.
