Internally connected to PTE1/RxD (MCU) and RxD (Analog Die), with PTE1/RxD (MCU) set as input.
Table 3. Static Electrical Characteristics (continued)
All characteristics are for the analog die only. Refer to the 68HC908EY16A datasheet for characteristics of the microcontroller
die. Characteristics noted under conditions 5.5 V
≤ VSUP ≤ 18 V, -40°C ≤ TJ ≤ 125°C, unless otherwise noted. Typical values
noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.
