Figure 6-30 Auxiliary I/O Bit Set Menu
The I/O pin is toggled between input and output when its corresponding bit number is selected. The
first line of the display shows the current status of the I/O control.
(P) POWERUP DEFAULTS MENU
Selecting this option allows the power up states of the I/O lines to be configured. If an I/O line is set
as an input then it cannot be configured to be high or low at power up, since it is a high impedance
input. Therefore, the status will not change when the I/O port numbers are selected. The settings are
toggled between low and high every time the I/O port number is selected. An example of the menu is
shown in Figure 6-31.
