MPFB Jumper Headers
Configure your MPFB jumper headers per the instructions in Table 3-1. Table 3-1
contains information exclusively intended for quick start and ignores the other
jumper headers.

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.
Install a jumper on pins 1 and 2 to indicate that the memory devices in the
pseudo ROM sockets (U2 & U4) have 28 pins.
Install a jumper on pins 1 and 2 to set the pseudo ROM port size (memory data
width) as 16 (word).
Install a jumper on pins 2 and 3 to enable the PRU.
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.
The default setting configures the MC68HC16R3 MCU as 16-bit, expanded
mode with these functions:
• CSBOOT = 16-bit port
• Chip select active
• Internal ROM disabled
• CSE and CSM active
Install a jumper on pins 1 and 2 to indicate that RAM is installed in the pseudo
ROM sockets (U2 & U4).
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.
