GENERAL RELEASE SPECIFICATION
MC68HC05CL48
GENERAL DESCRIPTION
MOTOROLA
REV 2.0
1-9
1.4.17 RT_L
This pin should be connected with an external pull-up resistor to vDD. This pin will
be pulled low when RDI1 rises above one volt.
1.4.18 RD1, RD2
These inputs are incoming ring qualiers.
1.4.19 BP0 - BP15
These are the back plane drivers dedicated to the LCD subsystem. BP8 - BP15
will be used as FP45 - FP52 when the LCD driver is only driving 8 back planes.
1.4.20 FP0 - FP44
These are the front plane drivers dedicated to the LCD subsystem.
1.4.21 VLCD, V0, V1, V2, V3, V4
VLCD is the power supply input for the LCD voltage generator. V0, V1, V2, V3 and
V4 are the internal resistor ladder node voltage. An external cap with one terminal
connected to GND should be connected to each of these four pins.
1.4.22 XFC
One terminal of the Phase-Locked Loop external capacitor should be connected
here, the other terminal should be connected to GND.
XFC
0.1uF
Phase-Locked Loop External Capacitor
