mikroBUS 1 slot
This slot is connected to the Flexcomm interface
0
, cannot be used as
SPI
standard
simultaneously with FTDI-SPI function, which shares
GPIO4
. However,
mikroBUS1 can still be used as UART or I2C standards with 2WCI-2 function.
To enable this slot:
•
The USB switch
U18
(default connection)
disconnect
R255
and populate
R256
with
0R.
•
Disconnect R8, R9, R38, R37, R259, R261 and populate R260, R262 with 0R.
•
Check jumpers
J25, J27, J80, J83, J84, J85, J89, J92
and resistors
R67, R71
to match
the required operation, as described in
and
