Note:

The electrical characteristics for the MC68HC05X16 should not be used for the

MC68HC705X32. Section B.9.2 and Section B.9.5 contain data speciﬁc to this device.

B.2

VPP6

The VPP6 pin is the voltage input for the EPROM in both read and programming modes (see

Section B.5).

B.3

CANE

This pin is the MCAN enable input. If CANE is connected to VDD, the internal MCAN module is

selected and its registers are mapped at addresses $0020 to $003D.

Note:

Although this pin can be left ﬂoating to disconnect the MCAN module, it is advisable to

connect it to VSS when the module is not in use.
