An alternate configuration for the 8900 lets the BDM and GPS receivers
operate independently, whereby the GPS receiver accepts differential cor-
rections from an external device rather than the internal BDM receiver.
This is configuration 6: For this configuration, pin 23 is grounded and
pins 11 and 24 are left open. Pin connections for configuration 6 are
described below in Table 17 (functions highlighted in bold indicate the
suggested pins for a normal installation, and are the minimum connec-
tions required for operation of the 8900):

Input signals may be connected to any appropriately labeled input pin;
output signals may be taken from any appropriately labeled output pin.
