Figure 28.5 shows an example of operations in deep standby mode when the IOKEEP and OPE
bits are set to 1 in external extended mode.
In this example, deep software standby mode is entered with the IOKEEP and OPE bits set to 1,
and then exited at the rising edge of the NMI pin. In external expansion mode, while the IOKEEP
bit is set to 1, retention of the states of pins for the address bus, bus-control signals (CS0, AS, RD,
HWR, and LWR), data bus is released after the oscillation settling time has elapsed. For other
pins, including the Bφ output pin, retention is released when the IOKEEP bit is cleared to 0, and
then they are set according to the I/O port or peripheral module settings.
