v1.1
If the MPU overwrites the CE’s working RAM, the CE’s output may be corrupted. If the CE is dis-
abled, the first 0x40 bytes of RAM are still unusable because the 71M6533/71M6534 ADC writes to
these locations.
The 80515 writes into external data memory when the MPU executes a MOVX @Ri,A or MOVX
@DPTR,A instruction. The MPU reads external data memory by executing a MOVX A,@Ri or MOVX
A,@DPTR instruction (SFR PDATA provides the upper 8 bytes for the MOVX A,@Ri instruction).

MOVX Addressing
There are two types of instructions differing in whether they provide an 8-bit or 16-bit indirect address to
the external data RAM.
In the first type, MOVX A,@Ri, the contents of R0 or R1 in the current register bank provide the eight
lower-ordered bits of address. The eight high-ordered bits of the address are specified with the PDATA
SFR. This method allows the user paged access (256 pages of 256 bytes each) to all ranges of the
external data RAM.
In the second type of MOVX instruction, MOVX A,@DPTR, the data pointer generates a 16-bit address.
This form is faster and more efficient when accessing very large data arrays (up to 64 KB), since no
additional instructions are needed to set up the eight high ordered bits of the address.
It is possible to mix the two MOVX types. This provides the user with four separate data pointers, two
with direct access and two with paged access, to the entire 64 KB of external memory range.
Dual Data Pointer
The Dual Data Pointer accelerates the block moves of data. The standard DPTR is a 16-bit register that
is used to address external memory or peripherals. In the 80515 core, the standard data pointer is called
DPTR, the second data pointer is called DPTR1. The data pointer select bit, located in the LSB of the DPS
register (DPS[0]), chooses the active pointer. DPTR is selected when DPS[0] = 0 and DPTR1 is selected
when DPS[0] = 1.
