A summary of the registers associated with the MEBI sub-block is shown in
descriptions of the registers and bits are given in the subsections that follow. On most chips the registers
are mappable. Therefore, the upper bits may not be all 0s as shown in the table and descriptions.

Pin Functions
MC9S12C-Family / MC9S12GC-Family
General-purpose I/O pin, see PORTE and DDRE registers.
Bus timing reference clock, can operate as a free-running clock at the system
clock rate or to produce one low-high clock per visible access, with the high
period stretched for slow accesses. ECLK is controlled by the NECLK bit in
PEAR, the IVIS bit in MODE, and the ESTR bit in EBICTL.
General-purpose I/O pin, see PORTE and DDRE registers.
Low strobe bar, 0 indicates valid data on D7–D0.
In special peripheral mode, this pin is an input indicating the size of the data
transfer (0 = 16-bit; 1 = 8-bit).
In expanded wide mode or emulation narrow modes, when instruction tagging
is on and low strobe is enabled, a 0 at the falling edge of E tags the low half of
the instruction word being read into the instruction queue.
General-purpose I/O pin, see PORTE and DDRE registers.
Read/write, indicates the direction of internal data transfers. This is an output
except in special peripheral mode where it is an input.
General-purpose input-only pin, can be read even if IRQ enabled.
Maskable interrupt request, can be level sensitive or edge sensitive.
General-purpose input-only pin.
Non-maskable interrupt input.
General-purpose I/O pin, see PORTK and DDRK registers.

General-purpose I/O pin, see PORTK and DDRK registers.
