 Load 
 immediate instruction 

 MVI Imm, [d], S 

 Stores Imm (immediate) 
 data in the data RAM or register specified by [d] only when S (sign flag) of the program control port is 1. 

 MVI Imm, [d], NS 

 Only when S (sign flag) of program control port is 0, Stores Imm (immediate) 
 data in the data RAM or register specified by [d]. 

 MVI Imm, [d], C 

 Only when C (carry flag) of the program control port is 1. The data of Imm (immediate) 
 is stored in the data RAM or register specified by [d]. 

 MVI Imm, [d], NC 

 Only when C (carry flag) of the program control port is 0, The data of Imm (immediate) 
 is stored in the data RAM or register specified by [d]. 

 MVI Imm, [d], TO 

 Program control port TO (D0 bus DMA execution flag) is 1 Only occasionally, Imm (immediate 
 ate) data is stored in the data RAM or register specified by [d]. 

 MVI Imm, [d], NTO 

 Program control port TO (D0 bus DMA execution flag) is 0 Only occasionally, Imm (immediate 
 ate) data is stored in the data RAM or register specified by [d]. 

 MVI Imm, [d], ZS 

 Either Z (zero flag) or S (sign flag) of the program control port When is 1, only 
 is stored in the data RAM or register specified by [d] 
 for Imm (immediate) data. 

 MVI Imm, [d], NZS 

 Program control port Z (zero flag) and S (sign flag) are both Only when 0, 
 Imm (immediate) data is stored in the data RAM or register specified by [d]. 

 DMA instruction 

 DMA D0, [RAM], SImm 

 SImm (Short immediate) data is set in the transfer word counter 
 ([TN0]) as a transfer counter, and externally to the RAM area specified by [RAM] using the D0 bus Data 
 is transferred. The transfer start address ([RA0]) and transfer word count counter ([TN0]) are updated to the values ​​at the end of transfer 
. 

 DMA [RAM], D0, SImm 

SImm (short immediate) data is set in the transfer word count counter ([TN0])
as a transfer counter, and data is transferred to the outside from the RAM area
specified by [RAM] using the D0 bus. The transfer start address ([WA0]) and
transfer word count counter ([TN0]) are updated to the values at the end of transfer.
