Instructions that use direct addressing access SFR space. For example: MOV 0A0H, # data,
accesses the SFR at location 0A0h (which is P2).
Instructions that use indirect addressing access the Upper 128 bytes of data RAM. For
example: MOV atR0, # data where R0 contains 0A0h, accesses the data byte at address
0A0h, rather than P2 (whose address is 0A0h).
The ERAM bytes can be accessed by indirect addressing, with EXTRAM bit cleared and
MOVX instructions. This part of memory which is physically located on-chip, logically
occupies the first bytes of external data memory. The bits XRS0 and XRS1 are used to hide a
part of the available ERAM as explained in Table 12-1. This can be useful if external
peripherals are mapped at addresses already used by the internal ERAM.
With EXTRAM = 0, the ERAM is indirectly addressed, using the MOVX instruction in
combination with any of the registers R0, R1 of the selected bank or DPTR. An access to
ERAM will not affect ports P0, P2, P3.6 (WR) and P3.7 (RD). For example, with EXTRAM =
0, MOVX atR0, # data where R0 contains 0A0H, accesses the ERAM at address 0A0H rather
than external memory. An access to external data memory locations higher than the
accessible size of the ERAM will be performed with the MOVX DPTR instructions in the same
way as in the standard 80C51, with P0 and P2 as data/address busses, and P3.6 and P3.7
as write and read timing signals. Accesses to ERAM above 0FFH can only be done by the
use of DPTR.
With EXTRAM = 1, MOVX @Ri and MOVX @DPTR will be similar to the standard 80C51.
MOVX at Ri will provide an eight-bit address multiplexed with data on Port0 and any output
port pins can be used to output higher order address bits. This is to provide the external
paging capability. MOVX @DPTR will generate a sixteen-bit address. Port2 outputs the high-
order eight address bits (the contents of DPH) while Port0 multiplexes the low-order eight
address bits (DPL) with data. MOVX at Ri and MOVX @DPTR will generate either read or
write signals on P3.6 (WR) and P3.7 (RD).
The stack pointer (SP) may be located anywhere in the 256 bytes RAM (lower and upper RAM)
internal data memory. The stack may not be located in the ERAM.
The M0 bit allows to stretch the ERAM timings; if M0 is set, the read and write pulses are
extended from 6 to 30 clock periods. This is useful to access external slow peripherals.
