7: Configurable Pin Manager
xPico® Wi-Fi® Embedded Device Server User Guide 44
Note: To modify a CP, all roles in which it is a member must be disabled.
Note: The changes to a CP configuration are not saved in FLASH. Instead, these CP
settings are used when the CP is added to a CP Role. When the CP Role is saved, its CP
settings are saved with it. Thus, a particular CP may be defined as "Input" in one role but
as "Output" in another. Only one role containing any particular CP may be enabled at
once.
Roles
The CP Role settings allow for the management of CP roles. Roles are configurable, may be
enabled or disabled and can be assigned or unassigned to a configurable pin. A role, based on its
state, can trigger outside events. Only an enabled role can be a trigger.
xPico Wi-Fi roles available for assignment to a configurable pin include the following:
Role AP Trigger
Role Line 1 DSR
Role Line 1 DTR
Role Line 2 DSR
Role Line 2 DTR
Role Line 2 Flow.CTS
Role Line 2 Flow.RTS
Role SPI.CS
Role SPI.INT
Role SPI.MISO

The items listed in the Table 7-3 can be configured for each role.
