(1) The sensor current I_SENSOR is consumed if (ADC10ON = 1 and REFON = 1) or (ADC10ON = 1 and INCH = 0Ah and sample signal is
high). When REFON = 1, I_SENSOR is included in I_REF+. When REFON = 0, I_SENSOR applies during conversion of the temperature sensor
input (INCH = 0Ah).
(2) The following formula can be used to calculate the temperature sensor output voltage:
V_Sensor,typ = TC_Sensor (273 + T [°C] ) + V_{Offset,sensor} [mV] or
V_Sensor,typ = TC_Sensor T [°C] + V_Sensor(T_A = 0°C) [mV]
(3) The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time t_SENSOR(on).
(4) No additional current is needed. The V_MID is used during sampling.
(5) The on-time t_VMID(on) is included in the sampling time t_VMID(sample); no additional on time is needed.

(1) The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming
methods: individual word/byte write and block write modes.
(2) These values are hardwired into the Flash Controller's state machine (t_FTG = 1/f_FTG).
