1. Timing Reference uses 0.9 V
2. Interrupt request through Port 3 (P33:P31).
3. SMR – bit 5 = 1.
4. SMR – bit 5 = 0.
5. If bit 1 of the SMR register is programmed to 1, this value is 2.5 ms as measured from the time the 
oscillator input to XTAL1 reaches a peak to peak voltage oscillation of at least 300 mV.
