1.3 Slow-Mode Clock Divider Advisory
Current versions of the M68HC12B-series devices include a slow-mode clock divider feature. This feature
is fully described in
located at $00E0. Older device mask sets do not support the slow-mode clock divider feature. This
register address is reserved in older devices and provides no function.
Mask sets that do not have the slow-mode clock divider feature on the MC68HC912B32 include: G96P,
G86W, and H91F.
Mask sets that do not have the slow-mode clock divider feature on the MC68HC12BE32 include: H54T
and J38M.
Mask sets that do not have the slow-mode clock divider feature on the MC68HC(9)12BC32 include: J15G.
