Wireless Charging
Figure 6 shows pin-to-pin connections between the BCM4356 and BCM59350, which consist of the following:
• Two Broadcom Serial Control (BSC)¹ data and clock lines.
• Two DC power supply lines.
• One interrupt (INTb) to the WLAN chip.
• One GPIO line, which is passed through an OR gate along with another signal from the application
processor AP. This is for BT_REG_ON function, as illustrated in Figure 6.
