7 Jumpers

Jumpers (or shorting headers) are small connectors that allow to choose from two or more options available. Jumpers are usually
installed during board assembly and do not require any changes. In the FRWY-LS1046A, all jumpers are 2-pin connectors with
two settings: open and shorted.

8 DIP switch

The FRWY-LS1046A has a 10-pin dual inline package (DIP) switch, SW1, which helps to perform some most common board
configuration tasks. For SW1:

Jumper settings
• Open: UART1 port is accessed remotely
through a 1x4 header (J73)
• Shorted: USB 2.0 micro-B connector (J58)
is connected to UART1 port through a
USB-to-UART bridge (default setting)
• Open: VDD = 0.9 V
• Shorted: VDD = 1 V (default setting)
• Open: RESET_REQ_B pin of the
processor is disconnected
• Shorted: RESET_REQ_B pin triggers
system reset when asserted (default
setting)
• Open: PROG_MTR pin of the processor is
powered off (default setting)
• Shorted: PROG_MTR pin is powered by
OVDD (1.8 V)
• Open: TA_BB_VDD pin of the processor is
powered off
• Shorted: TA_BB_VDD pin is powered by
VDD (1/0.9 V) (default setting)
