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

W6 selects the MCU operation mode. Each 3-pin jumper header set
corresponds to an MCU data line. While the reset pin is low, the reset data
values are driven on the data bus (D0 – D15). (The MEVB reset data circuit is
open drain; a high state is provided via a pull-up resistor.) Each reset data line
may be set high (H) or low (L). Consult the appropriate MCU user's manual,
data book, or technical summary for reset data information.
