11.3 General-Purpose Input Port (P0D, P1A, P1C)
11.3.1 Configuration of input port
The following paragraphs (1) and (2) show the configuration of the input port.
(1) P0D (P0D3, P0D2, P0D1, P0D0)
Note
This is an internal signal output on execution of the clock stop instruction, and its circuit is
designed not to increase the current consumption due to noise even if the pin is floated.
(2) P1A (P1A3, P1A2, P1A1, P1A0)
P1C (P1C3, P1C2, P1C1, P1C0)
Note
This is an internal signal output on execution of the clock stop instruction, and its circuit is
designed not to increase the current consumption due to noise even if the pin is floated. (Except
P1A3, P1A2, P1A0)
