Install a jumper on pins 1 and 2 to configure pin 1 of the memory devices in the
pseudo ROM sockets (U2 & U4) as a standard address line.
W3
1 2 3
Install a jumper on pins 1 and 2 to indicate that the memory devices in the
pseudo ROM sockets (U2 & U4) have 28 pins.
W4
1 2 3
Install a jumper on pins 1 and 2 to set the pseudo ROM port size (memory data
width) as word.
W5

Install a jumper on pins 3 and 4 to indicate that the two devices installed in the
pseudo ROM sockets (U2 & U4) are 32K x 8.
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.
