Software programmable port 2. If SWPORT2 = 0, then pin SWPORT2 is inactive
(high-impedance). If SWPORT2 = 1, then pin SWPORT2 is active (pull down to ground).
Software programmable port 1. If SWPORT1 = 0, then pin SWPORT1 is inactive
(high-impedance). If SWPORT1 = 1, then pin SWPORT1 is active (pull down to ground).
This bit is not used and should be set to logic 0.
Setting of crystal frequency DAA. These 5 bits determine the crystal frequency
alignment output voltage.
Chip ID. These bits contain a constant value (0010 0001 = 21H) for chip identification
purposes.
