eMIOS200 B Register (EMIOS_CBDR[n])
Depending on the mode of operation, internal registers B1 or B2 can be assigned to address
EMIOS_CBDR[n]. Both B1 and B2 are cleared by reset.
summarizes the EMIOS_CBDR[n]
writing and reading accesses for all operation modes. For more information see section
“Unified Channel Modes of Operation
Depending on the channel configuration, it may have EMIOS_CBDR register or not. This means that if at
least one mode that requires the register is implemented, then the register is present, otherwise it is absent.
Offset: UC[n] base a 0x0004
Access: User read/write
