Clock Source Select Header (P6)

Jumper header P6 determines the source of the clock signal. The dia-
gram below shows the factory configuration: the fabricated jumper
between pins 2 and 3 selects the L1EM canned oscillator clock source.
This is the only correct configuration for an L1EM that is part of an
HC05EVS.

NOTE

The P6 pins 1 and 2 configuration is not correct for an
L1EM that is part of an HC05EVS system.
