48.2 Register Descriptions
48.2.1 DOC Control Register (DOCR)
Note 1. Valid only when data comparison mode is selected.
OMS[1:0] Bits (Operating Mode Select)
These bits select the operating mode of the data operation circuit.
DCSEL Bit (Detection Condition Select)
This bit is valid only when data comparison mode is selected.
This bit selects the condition for detection in data comparison mode.
DOPCIE Bit (Data Operation Circuit Interrupt Enable)
Setting this bit to 1 enables interrupts from the data operation circuit.
DOPCF Flag (Data Operation Circuit Flag)
[Setting conditions]
The condition selected by the DCSEL bit is met
A result of data addition is greater than FFFFh
A result of data subtraction is less than 0000h
[Clearing condition]
Writing 1 to the DOPCFCL bit
DOPCFCL Bit (DOPCF Clear)
Setting this bit to 1 clears the DOPCF flag.
This bit is read as 0.
