Ground connection.
SCL, SDA
11,13
I
2
C™ interface, 5V logic.
MOSI,
MISO, SCK
17,19,21 SPI interface, 5V logic (used for SSC EB identification by I
2
C™; not applicable to ZSSC4151).
OWI

G3 low via the
PS_G30
terminal command.
ADC1
27
One-Wire Interface (OWI) connection to CB’s ADC1 (PA1).
PE7
28
Bi-directional I/O port with internal pull-up resistors.
Tr_PD2
39
Pull-
up from KS5V with 510Ω resistor (R2) to the OWI line; enabled by setting the SSC CB
microprocessor port pin D2 low via the
PS_D20
terminal command during OWI communication.
PD4
43
Bi-directional I/O port with internal pull-up resistors.
PD6, PD7
47,49
I
2
C™ 8-bit serial shift registers settings; set by the ZSSC4151 Evaluation Software.
