DMA transfer SFR start address registers 2, 3 (SAR2, SAR3)
The SARn register specifies the start address of the TMR register for which the DMA transfer is
started on DMA channel n (n = 2, 3).
This register can be read or written in 8-bit units.
After reset the register content is undefined.
Figure 6-2:
DMA Transfer SFR Start Address Registers 2, 3 (SAR2, SAR3)
Notes: 1.
Although the register address is meaningless, a transfer to this address is always
performed when SARn2 to SARn0 bits are equal to 010B or less.
2.
Although the register address is meaningless, a transfer to this address is always
performed when SARn2 to SARn0 bits are equal to 011B or less.
Caution:
During DMA transfer (DEn = 1) the contents of the SARn register may change.
After each DMA transfer the contents is incremented by 1 until the final value (07H)
is reached.
When the SARn register contents becomes 07H, the initial set value is reloaded.
After reset:
