CORADm - VFB flash/ROM “DBTRAP” ROM Correction address register
These registers hold the address where the VFB flash/ROM correction should
be performed.
Access
These registers can be read/written in 32-bit (CORADm) and 16-bit units
(CORADmL for bits 15 to 0, CORADmH for bits 31 to 16).

Caution
The ROM correction address CORADm[19:0] must not exceed the upper
address of the internal ROM respectively flash memory.
If the internal ROM/flash memory size is less than 1 MB the appropriate
number of upper address bits of CORADm[19:0] must be set to 0.
Note
CORADm shall only be changed when the corresponding channel is disabled
(CORCN.CORENm = 0).
