Bit Name
Function
CORADm
Lower 16 bit of the ROM correction address of channel m.
[19:0]
Bit 0 and bits 31 to 20 are fixed to 0, writing to these bits is ignored.
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).
