Port B has different pin functions in different modes. A separate description for each mode is
given below.
Pin Functions in Modes 1 and 2: In mode 1 (expanded mode with on-chip ROM disabled) and
mode 2 (expanded mode with on-chip ROM enabled), when the host interface enable bit (HIE) is
cleared to 0 in the system control register (SYSCR), port B is a general-purpose input/output port.
When the HIE bit is set to 1, selecting slave mode, port B becomes the host interface data bus
(XDB
section 14, Host Interface.
Figure 7.20 shows the pin functions in modes 1 and 2.
