7.4.1.14 INPUT PORT (IP). The IP register shows the current state of the

CTS

≈ inputs.

This register can only be read when the serial module is enabled (i.e., the STP bit in the

MCR is cleared).

CTSB, CTSA—Current State

1 = The current state of the respective

CTS

≈ input is negated.

0 = The current state of the respective

CTS

≈ input is asserted.

The information contained in these bits is latched and reflects the state of the input pins

at the time that the IP is read.

NOTE

These bits have the same function and value of the IPCR bits 1

and 0.
