8.4.9 CGM External Connections
8.5 I/O Signals
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
In its typical configuration, the CGM requires up to four external
components.
Figure 8-3
Care should be taken with PCB routing in order to minimize signal cross
talk and noise. (See
routing information, filter network and its effects on PLL performance.)
The following paragraphs describe the CGM I/O signals.
