Reset: P4DDR and P4DR and the 8-bit timer control registers are initialized, making pins P4
to
0
P4
into input port pins with the MOS pull-ups off. When the chip comes out of reset into single-
5
chip mode (mode 3), P4
and P4
also become input port pins with the MOS pull-ups off. When the
6
7
chip comes out of reset into an expanded mode (mode 1 or 2), the system clock and E clock are
output at P4
and P4
.
6
7
Hardware Standby Mode: All pins are placed in the high-impedance state with the MOS pull-ups
off.
Software Standby Mode: The 8-bit timer control registers are initialized but P4DDR and P4DR
remain in their previous states. Pins P4
to P4
become input or output port pins depending on the
0
5
setting of P4DDR. Pins P4
and P4
remain in their previous states, with system clock output
6
7
remaining high and E clock output remaining low. The MOS pull-ups of input pins are on or off
depending on the values in P4DR.
Figures 5-4 to 5-7 show schematic diagrams of port 4.
