Table 1. Summary of MC68HC908JB12 and MC68HC908JB16 Differences
(1)
This section introduces the MC68HC908JB12, a derivative of the
MC68HC908JB16. The entire MC68HC908JB16 data book, including the
updates in this addendum, applies to this device, with exceptions outlined
below.

Figure 4
The dual 27-MHz clock generator module on the MC68HC908JB16 is not
designed in the MC68HC908JB12, hence, register locations from $0051 to
$0059 are unimplemented. Information in the data book relating to the CGM do
not apply to the MC68HC908JB12.
