Bit [7:0] : Global Select [7:0] When written determines whether a pin is connected to the Global Input Bus and Glo-
bal Output Bus
0 = Not Connected
1 = Connected
Drive Mode xx = Global Select Register 0 = Standard CPU controlled port (Default)
Drive Mode 1 0 (High Z) = Global Select Register 1 = Direct Drive of associated Global Input line
Drive Mode 0 0, 0 1, 1 1 = Global Select Register 1 = Direct Receive from associated Global Output line
Bit [7:0] : DM0 [7:0] The two Drive Mode bits that control a particular port pin are treated as a pair and are decoded
as follows:
Port Data Register Bit 0 = Drive Mode 0 0 = 0 Resistive (Default)
Port Data Register Bit 0 = Drive Mode 0 1 = 0 Strong
Port Data Register Bit 0 = Drive Mode 1 0 = High Z
Port Data Register Bit 0 = Drive Mode 1 1 = 0 Strong
Port Data Register Bit 1 = Drive Mode 0 0 = 1 Strong
Port Data Register Bit 1 = Drive Mode 0 1 = 1 Strong
Port Data Register Bit 1 = Drive Mode 1 0 = High Z
Port Data Register Bit 1 = Drive Mode 1 1 = 1 Resistive
