CMP0CON0 is a special function register (SFR) to control the comparator.
[Description of Bits]
• CMP0EN (bit 0)
The CMP0EN bit is used to control ON/OFF of the comparator 0.When CMP0EN is set to "1", the comparator 0 is
turned on. When it is set to "0", the comparator 0 is turned off.
CMP0EN
0 Comparator 0 OFF (initial value)
1 Comparator 0 ON
• CMP0D (bit 1)
CMP0D indicates the status of the comparator 0 output (CMP0OUT in Figure 22-1).It is set to "1" when the PB4 pin
voltage is higher than the PB5 pin voltage (PB4>PB5). It is set to "0" when the PB4 pin voltage is lower than the PB5 pin
voltage (PB4<PB5).It holds the last status even after the comparator 0 is turned off (CMP0EN is set to "0").
