1
V_IN
Connects the Daughter Card to the
supply voltage output on the
M52235EVB.
Provides supply voltage to the Daughter Card.
Voltage must not exceed 16 Vdc. See
Section 5.1.0.3, “Power Connections”
.
2
IRQ
Connects to IRQ pin of MC1320X. Allows the MC1320X to issue an IRQ to the
MCU.
3
GND
Connects the ground of the RF
Daughter Card to the ground of the
M52235EVB
9
GPIO1
Connects to General Purpose
Input/Output 1 of MC1320X.
When gpio_alt_en, Register 9, Bit 7 = 1,
GPIO1 functions as an “Out of Idle” Indicator.
10
GPOI2
Connects to General Purpose
Input/Output 2 of MC1320X.
When gpio_alt_en, Register 9, Bit 7 =1,
GPIO2 functions as a “CRC Valid” Indicator.
13
RESET
Connects to RESET of MC1320X
and Pin 32 of J101.
Allows the MCU to reset the MC1320X.
15
PTD5/CESI
Connects to ATTN of MC1320X
and Pin 34 of J101.
Allows the MCU to wake up the MC1320X
from Doze or Hibernate.
17
MOSI
Connects to MOSI of MC1320X.
SPI
19
MISO
Connects to MISO of MC1320X.
SPI
20
RXTXEN
Connect to RXTXEN of MC1320X. Allows the MCUntrol the RXTXEN line of the
MC1320X.
21
SPICLK
Connect to SPICLK of the
MC1320X
SPI
23
