Selecting the CAx input pin to the comparator multiplexer with the P2CAx bits automatically disables the input buffer for that pin, regardless of the state of the associated CAPD.x bit. (5) In JTAG mode the internal pullup/down resistors are disabled. (6) Function controlled by JTAG Copyright © 2005–2011, Texas Instruments Incorporated 53 |
