The SCP can be configured to operate in a local loopback mode, which is useful for local
diagnostic functions.
Note that the least significant bit of the SCP is labeled as data bit 0 on the serial line; where-
as, other devices, such as the MC145554 CODEC, may label the most significant bit as data
bit 0. The MC68302 SCP bit 7 (most significant bit) is shifted out first.
The SCP key features are as follows:
MOTOROLA
• Three-Wire Interface (SPTXD, SPRXD, and SPCLK)
• Full-Duplex Operation
• Clock Rate up to 4.096 MHz
• Programmable Clock Generator
• Local Loopback Capability for Testing
