Description
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.
Description
Chip ID. These bits contain a constant value (0010 0001 = 21h) for
chip identification purposes.
