3. Central Processing Unit (CPU)
(9) Save PC register (SVP)
This register consists of 24 bits and is used to save the program counter when a high-speed interrupt is
generated.
(10) Vector register (VCT)
This register consists of 24 bits and is used to indicate the jump address when a high-speed interrupt is
generated.
(11) DMA mode registers (DMD0/DMD1)
These registers consist of 8 bits and are used to set the transfer mode, etc. for DMA.
(12) DMA transfer count registers (DCT0/DCT1)
These registers consist of 16 bits and are used to set the number of DMA transfers performed.
(13) DMA transfer count reload registers (DRC0/DRC1)
These registers consist of 16 bits and are used to reload the DMA transfer count registers.
(14) DMA memory address registers (DMA0/DMA1)
These registers consist of 24 bits and are used to set a memory address at the source or destination of
DMA transfer.
(15) DMA SFR address registers (DSA0/DSA1)
These registers consist of 24 bits and are used to set a fixed address at the source or destination of DMA
transfer.
(16) DMA memory address reload registers (DRA0/DRA1)
