• Description: Single-phase Energy Measurement Ic With 8052 Mcu, Rtc And Lcd Driver
• Manufacturer: Analog Devices, Inc.

Preliminary Technical Data
To illustrate the operation of DPCON, the following code copies
256 bytes of code memory at Address D000H into XRAM,
starting from Address 0000H.
MOVELOOP: CLR A
Whenever the DPTR is mentioned elsewhere in this data
sheet, active DPTR is implied.
Only the MOVC/MOVX @DPTR instructions
automatically post-increment and post-decrement the
DPTR. Other MOVC/MOVX instructions, such as MOVC
PC or MOVC @Ri, do not cause the DPTR to automatically
post-increment and post-decrement.
