Jumper header P5 is for factory test use only and should be used only by
Motorola factory personnel.
If the factory setting is changed, proper operation of the system cannot be
guaranteed. Figure 2-2 shows the default factory jumper header configuration,
which has no fabricated jumper installed on jumper header P5 between pins 1
and 2.
Use jumper header P8 to select the power source for the MCU internal
analog-to-digital (ADC) module
Install a jumper on jumper header P8 (factory default) when V
supplied from the target system. This allows use of the ADC module in the
MC68HC908GP32 or MC68HC908GP20 MCUs when there is no target
system V
Remove the jumper on jumper header P8 when V
system and an MC68HC908GP32 or MC68HC908GP20 MCU is being used.
Because V
MCU, the jumper on P8 must be installed when emulating JL3.
Alternately, remo
ve the jumper from P8 and connect an external power supply to P8 pin 1.
