CHAPTER 3 PIN FUNCTION (
µ
PD78014 Subseries)
73
3.2.13 XT1 and XT2
Crystal resonator connection pins for subsystem clock oscillation.
For external clock supply, input it to XT1 and its inverted signal to XT2.
3.2.14 V
DD
Positive power supply pin
3.2.15 V
SS
Ground potential pin
3.2.16 V
PP
(
µ
PD78P014 only)
High-voltage apply pin for PROM programming mode setting and program write/verify. Connect directly to V
SS
in normal operating mode.
3.2.17 IC (Mask ROM version only)
The IC (Internally Connected) pin sets a test mode in which the
µ
PD78011B, 78012B, 78013 and 78014 are tested
before shipment. In normal operation mode, connect the IC pin directly to V
SS
with as short a wiring length as possible.
If there is a potential difference between the IC and V
SS
pins because the wiring length between the IC and V
SS
pins is too long, or external noise is superimposed on the IC pin, your program may not run correctly.
• Directly connect the IC pin to the V
SS
.
