Description
B12
CMOS input with weak
internal pull-down
Reset if high. Input debounced so must be
high for >5ms to cause a reset
E12
CMOS input with weak
internal pull-up
Reset if low. Input debounced so must be
low for >5ms to cause a reset
C11
CMOS input with weak
internal pull-up
Chip select for Synchronous Serial Interface
active low
C13
CMOS input with weak
internal pull-down
Serial Peripheral Interface clock
D12
CMOS input with weak
internal pull-down
Serial Peripheral Interface data input
B13
CMOS output, tri-state, with
weak internal pull-down
Serial Peripheral Interface data output
B11
CMOS input with strong
internal pull-down
