Note:
Preliminary electrical speciï¬cations for the MC68HC05B32 should be taken as being
similar to those for the MC68HC705B32. When silicon is fully available, the part will be
re-characterised and new data made available.
G.2
External clock
14
When using an external clock the OSC1 and OSC2 pins should be driven in antiphase (see
Figure D-2). The tOXOV or tILCH speciï¬cations (see Section H.9) do not apply when using an
external clock input. The equivalent speciï¬cation of the external clock source should be used in
lieu of tOXOV or tILCH.
