V_HYST	Hysteresis		20		mV	CTRLA.HYSMODE = 0x1, CTRLA.POWER = 0x0
			28			CTRLA.HYSMODE = 0x2, CTRLA.POWER = 0x0
			43			CTRLA.HYSMODE = 0x3, CTRLA.POWER = 0x0
t_RESP ⁽¹⁾*	Response time, rising edge		85		ns	CTRLA.POWER = 0x0, V_CM = V_DD/2
	Response time, falling edge		85		ns	CTRLA.POWER = 0x0, V_CM = V_DD/2
	Response time, rising edge		250		ns	CTRLA.POWER = 0x1, V_CM = V_DD/2
	Response time, falling edge		220		ns	CTRLA.POWER = 0x1, V_CM = V_DD/2
	Response time, rising edge		460		ns	CTRLA.POWER = 0x2, V_CM = V_DD/2
	Response time, falling edge		430		ns	CTRLA.POWER = 0x2, V_CM = V_DD/2
* These parameters are characterized but not tested. † Unless otherwise specified, data in the “Typ.” column is at T_A = 25°C and V_DD = 3.0V. Note: Response time is measured with one comparator input at V_DD/2 while the other input transitions from GND to V_DD.
