• a7-a0 (bits 7-0)
Address: 0F400H to 0F5FFH
Access: R/W
Access size: 8 bits
Initial value: Undefined
DSmCnA (m= 0 to 63, n = 0 to 7) are special function registers (SFRs) that are used for the programmable display
allocation function.
Each valid bit of DSmCnA becomes undefined at system reset.
When the programmable display allocation function is not used (DASN bit of DSPMOD1 reigster is reset to “0”),
DSmCnA can be used as data memory space (512-byte RAM).
Table 24-2 shows a list of the display allocation register A.
[Description of Bits]
Initial value
DSmCnA
The a7 to a0 bits of DSmCnA (m= 0 to 63, n = 0 to 7) are used to select the lower 8 bits of the addresses of the display
registers (DSPR00 to FE) that are output to common n of segment m.
Set DSmCnA when the DASN bit of the display mode register 1 (DSPMOD1) is “0”.
When the DASN bit is “1”, access from the CPU is invalid.
