instructions other than MOVX and MOVC. All or part of the Stack may be in this area.
idata
Indirect data; 256 bytes of internal data memory space (00h~FFh) accessed via indirect addressing using
instructions other than MOVX and MOVC. All or part of the Stack may be in this area. This area includes the
data area and the 128 bytes immediately above it.
sfr
Special Function Registers; CPU registers and peripheral control/status registers, accessible only via
direct addressing.
xdata
External data or on-chip eXpanded RAM (XRAM); duplicates the classic 80C51 64KB memory space
addressed via the “MOVX @DPTR” instruction. The CMT2380F17 has 768 bytes of on-chip xdata memory.
pdata
Paged (256 bytes) external data or on-chip eXpanded RAM; duplicates the classic 80C51 256 bytes
memory space addressed via the “MOVX @Ri” instruction. The CMT2380F17 has 256 bytes of on-chip pdata
memory which is shared with on-chip xdata memory.
code
16K bytes of program memory space; accessed as part of program execution and via the “MOVC
@A+DTPR” instruction. The CMT2380F17 has 16K bytes of on-chip code memory.
