F15
LED_RUN O
Run Status LED, connect to green LED (Cathode)
0 = LED on, 1 = LED off
E3
PDI_EMULATION I
Selects between
normal op
eration with state machine
inside ESC or device emulation mode (no µC required).
Has weak internal pull down.
0 = default, no device emulation, µC required
1 = device emulation
F3
PDI_EOF O Ethernet End-of-Frame if 1
G3
PDI_SHARED_SPI_BU
S
I
Selects between separate SPI busses (SDI, SDO, SCK) or
one SPI bus with two CS lines for the PDI and MFCIO
SPI interface: 0 = two separate SPI busses, 1 = one
shared SPI bus using the PDI_SPI_x bus lines (not the
PDI_MFC_SPI bus lines)
