Function
Strobe signal indicating that address output on the address
bus is enabled (when the IOSE bit in SYSCR is cleared to 0).
I/O select signal (when the IOSE bit in SYSCR is set to 1).
Strobe signal indicating that the external address space is
being read.
Strobe signal indicating that the external address space is
being written to, and the upper half (D15 to D8) of the data
bus is enabled.
Strobe signal indicating that the external address space is
being written to, and the lower half (D7 to D0) of the data bus
is enabled.
