Description
W14
1 2 3
Jumper header W14 selects the MCU signal for the memory devices in the fast
RAM sockets (U9 & U10) and pseudo ROM sockets (U2 & U4). Pins 1 and 2
select the MCU chip select for the memory devices in the fast RAM sockets.
Pins 2 and 3 of jumper header W14 select the chip select for the memory
devices in the pseudo ROM sockets.
Jumper installed on CSBOOT pins 2 and 3 (factory default); use CSBOOT as
the memory device chip enable for memory devices in the pseudo ROM
sockets.
W16
1 2
No jumper installed; the MCU MODCLK signal is pulled high (logic 1) via a
resistor during reset.
W17
1 2
No jumper installed; the BERR signal is pulled high (logic 1) via a resistor
during reset.
W18
1 2 3
Install a jumper on pins 1 and 2 for unrestricted writes to the memory devices
in the pseudo ROM sockets (U2 & U4).
W19
1 2 3
Install a jumper on pins 1 and 2 to ground the A19 signal to the MPFB memory
arrays.
W22
1 2 3
Install a jumper on pins 2 and 3 to select the evaluation MCU (on the MPB) as
an M68HC16 MCU device.
3.3 MEVB INSTALLATION INSTRUCTIONS
MEVB installation requires a user-supplied power supply and host computer. The
host computer must have the appropriate I/O port (serial or parallel) as required by
your debugger hardware; as well as the appropriate operating system as required
by your debugger software (refer to the appropriate debugger documentation for
these requirements). The following paragraphs explain MPFB connections. Refer
to Chapter 2 for instructions to connect the MPB and MPFB.
