• b2-b0 (bits 2-0)
Address: 0F600H to 0F7FFH
Access: R/W
Access size: 8 bits
Initial value: Undefined
DSmCnB (m= 0 to 49, n = 0 to 7) are special function registers (SFRs) to store segment allocation data.
Each valid bit of DSmCnB becomes undefined at system reset.
When the programmable display allocation function is not used (DASN bit of DSPMOD1 reigster is reset to “0”), DSmCnB
can be used as data memory space (512-byte RAM).
Table 26-3 shows a list of display allocation register B.
[Description of Bits]
Initial value
DSmCnB
The b2 to b0 bits of DSmCnB (m= 0 to 49, n = 0 to 7) are used to set the bits of the display registers (DSPR00 to 71) that
are output to common n of segment m.
Set DSmCnB when the DASN bit of the display control register 0 (DSPCON0) is “0”.
When the DASN bit is “1”, access from the CPU is invalid.
