5 Jumpers and Switches

This chapter describes the jumpers and switches which can be modified on the MB91V460
adapter board (MB2198-300). Also the jumpers of the evaluation board SK-91460-MAIN
V1.2 influencing the adapter board are explained. The default settings are mentioned.

5.1 Jumpers of the MB91V460 Adapter Board (MB2198-300)

5.1.1 V-Chip Options

Some options of the V-chip can be enabled or disabled.
Jumper
S1
ALARM_SEL
S2
ADC_SEL
S3
HWWDG_KILL
S4
FIX_ENX
S5
CSV_KILL
S6
SRAM_SFX
S7
FSC_DISABLE
Default:
S1 = X–DIS
S4 = EN–X
Note:
1) ALARM_SEL: The 91V460 is equipped with two different alarm comparators. The
devices 91F467D and 91461 are equipped with the new alarm comparator.
2) ADC_SEL: Depending on the voltage supply the respective ADC have to be
selected.
3) HWWDG_KILL: The hardware watchdog has to be enabled also in the Softune
workbench.
(Debug Mode: Setup-> Dev. Environment-> Dev. Environment-> Execution->
watchdog)
4) SRAM_SFX: Depending on the connected emulation memory, the respective mode
has to be selected. By default a SRAM is connected.
