3.6 Pin Status in Sleep, Stop, Hold and Reset Modes
181
Table 3.6.2 Pin Status in 8-Bit External Bus Mode
Note1:
Same as other ports when used for output port functions. 'Input enabled' means that input functions
are available for use. However, input is shut off when the corresponding interrupts are disabled.
Note2:
In this mode, the immediately preceding output values are retained and output. If in input state,
input is disabled. 'Input disabled' means that the first input gate at the pin is enabled for operation,
but that internal circuits are not operating so that the signal from the pin is not accepted internally.
Note3:
'Input shut off' means that the first input gate at the pin is disabled. 'Output Hi-Z' means that the
transistor driving the pin is disabled placing the pin in high-impedance state.
Note4:
'Output mode' means that the transistor driving the pin is in drive enabled state, but since the inter-
nal circuit operation is stopped, a fixed 'H' or 'L' value is output.
Note5:
'Output enabled' means that the transistor driving the pin is in drive enabled state, and because
internal circuit operations are enabled, the process of operation can be sensed from the pin.
Note6:
When used as a general-purpose port, the immediately prior status is retained.
