I am embedding a BS2 SSOP into my current project. It will not have any need to communicate to the outside world.
It's pretty clear as to what needs to be done with the following pins:
- pins 1,2,14 (Vss)
- pins 3,4 (Vdd)
- pin 5,6 (SDA, SCL for EEPROM)
- pins 26, 27 (X0, X1 for resonator)
- pin 28 (RESET/)
Not clear is what's to be done with pins 7 and 8 (Rx, Tx) since there will be no outside communication with the BS2. Pull them high, pull them low? Put 'em in a paper bag and swing it around my head while clucking like a chicken?***
Can anyone clarify?
