P6CNT.2–P6CNT.0
Bits 2–0 Port pin P6.3–P6.0 configuration control bits. P6CNT.2-0 determine whether specific P6 pins function
as program chip-enable signals or as I/O.
C0M6C
Bits 7–0 Operation of the bits in this register are identical to those found in the CAN 0 message 1 control regis-
ter (C0M1C: ABh). Consult the description of that register for more information.
