Source Address Reload Function
Channel 2 includes a reload function, in which the value is returned to the value set in the source
address register (SAR2) every four transfers by setting the RO bit in CHCR2 to 1. 16-byte transfer
cannot be used. Figure 11.22 shows this operation. Figure 11.23 shows a timing chart for the
source address reload function under the following conditions: burst mode, auto-request, 16-bit
transfer data size, SAR2 incremented, DAR2 fixed, reload function on, and use of channel 2 only.
