MCU reset boot configuration
8.1
Boot mode selection (J14, J15)
Vybrid has two boot-mode pins (BOOTMOD[0..1]) routed to jumpers J14 and J15 to determine the EVB
boot behavior (see
Table 15
). By default, boot configuration will be read from the internal fuses.
8.2
RCON configuration (SW8 to SW11)
In addition, there are 32 switches (four 8-way miniature slide switches as per
), which can be
used to setup the Vybrid RCON pins behavior prior to blowing its internal boot fuses (see
Table 3
), the ON
switch position meaning “Logic High” on the RCON pin.
Reset configuration is read from the RCON switches when BOOTMOD[0..1] is set to 10 and ignored for
the rest of the values (see
Table 15
).
