MOTOROLA
NDBE — No Data Bus Enable
CGMTE — Clock Generator Module Testing Enable
PIPOE — Pipe Status Signal Output Enable
NECLK — No External E Clock
In peripheral mode, the PEAR register is not accessible for reads or
writes. However, the CGMTE control bit is reset to one to configure
PE6 as a test output for the CGM module.
Normal: write once; Special: write anytime EXCEPT the first. Read
anytime.
The NDBE bit has no effect in Single Chip or Peripheral Modes and
PE7 is defaulted to the CAL function if CALE bit is set in PEAR
register or to an I/O otherwise.
Normal: write never; Special: write anytime EXCEPT the first time.
Read anytime.
Normal: write once; Special: write anytime EXCEPT the first time.
Read anytime.
Normal single chip: write once; special single chip: write anytime; all
other modes: write never.
Read anytime. In peripheral mode, E is an input and in all other
modes, E is an output.
