/*INTEL ICH4 South Bridge used to control cash drawer.
They are defined as below:
· GPI 32 CD_SW_AB input 1, high Drawer(s) CLOSED. Input 0,
low Drawer(s) OPEN.
· GPO 33 CD_SOL_A output 0, low turn off solenoid A. Output 1,
high Activates Solenoid A.
· GPO 34 CD_SOL_B output 0, low turn off solenoid B. Output 1,
high Activates Solenoid B.
. GPO 35 CD_ARM output 0, low activates driving circuit. Output 1, high
De-activates driving circuit.
