contain 128 directly addressable bit locations.The stack depth is
only limited by the available internal RAM space of 256 bytes.
XRAM0
The 256 bytes of XRAM0 used to support DDC interface is also
available for system usage by indirect addressing through the ad-
dress pointer DDCADR and data I/O buffer RAMBUF. The ad-
dress pointer(DDCADR) is equipped with the postincrement
capability to facilitate the transfer of data in bulk (for details refer
to DDC Interface part). However, it is also possible to address the
DRAM through MOVX command as usually used in the internal
RAM extension of 80C51 derivatives. XRAM0 0 to 255 is direct-
ly addressable as external data memory locations 0 to 255 via
MOVX-DPTR instruction or via MOVX-Ri instruction when the
EXCON’s LSB is zero. Since external access function is not
available, any access to XRAM0 0 to 255 will not affect the
ports.
