Device	StartAddr	Size	J-Link Support
GD32A503xB	0x08000000	128Kb	YES
GD32A503xC	0x08000000	256Kb	YES
GD32A503xD	0x08000000	384Kb	YES

Device	StartAddr	Size	J-Link Support
GD32A503xB	0x1FFFF800	24 Byte	YES
GD32A503xC	0x1FFFF800	24 Byte	YES
GD32A503xD	0x1FFFF800	24 Byte	YES

The device uses normal reset, no special handling necessary.

In order to prevent errors when reading first time, the DLL intialises the first 24Kb of RAM starting at 0x2000 0000.
