44. 12-Bit A/D Converter (S12ADE)
GBRSCN bit. The ADCSR.ADST bit must be 0 when the GBRP bit is to be set.
The setting of the GBRP bit is enabled when the PGS bit is 1.
44.2.18
A/D Compare Function Control Register (ADCMPCR)
ADCMPCR sets the compare window A and window B functions.
CMPAB[1:0] Bits (Window A/B Composite Condition Setting)
These bits are valid when both window A and window B are enabled (CMPAE = 1 and CMPBE = 1) in single scan mode.
These bits are used to select compare function match/mismatch event output conditions for the ELC or monitoring
conditions of ADWINMON.MONCOMB. The CMPAB[1:0] bits should be set while the ADCSR.ADST bit is 0.
CMPBE Bit (Compare Window B Operation Enable)
This bit enables or disables the compare window B operation. The CMPBE bit should be set while the ADCSR.ADST bit
is 0.
Set this bit to 0 before setting the following registers.
