18.4.1
The host interface is activated by setting the HI12E bit in SYSCR2 to 1 in single-chip mode.
When the host interface is activated, all related I/O ports (data port 3, control ports 8 and 9, and
host interrupt request port 4) become dedicated host interface ports. Setting the CS3E bit and
CS4E bit to 1 enables the number of host interface channels to be extended to four, and makes the
channel 3 and 4 related I/O port (part of port B for control and host interrupt requests) a dedicated
host interface port.
