•
The DARx register can be automatically reloaded from its initial value at the end of every block for multi-block transfers. A
new block transfer is then initiated.
• RELOAD_SRC: Automatic Source Reload
The SARx register can be automatically reloaded from its initial value at the end of every block for multi-block transfers. A
new block transfer is then initiated.
• SRC_HS_POL: Source Handshaking Interface Polarity
• DST_HS_POL: Destination Handshaking Interface Polarity
• HS_SEL_SRC: Source Software or Hardware Handshaking Select
This register selects which of the handshaking interfaces, hardware or software, is active for source requests on this
channel.
If the source peripheral is memory, then this bit is ignored.
• HS_SEL_DST: Destination Software or Hardware Handshaking Select
This register selects which of the handshaking interfaces, hardware or software, is active for destination requests on this
channel.
