PAN9026 Wi-Fi/BT Module
2 Overview
2.5 Peripheral Bus Interface
The Peripheral Bus Unit (PBU) connects several low speed peripherals to the internal bus of the
device. The device consists of the GPIO Interface and the One Time Programmable Memory.
Type
General Purpose I/O
(GPIO) Interface
One Time Programmable
Memory (OTP)
Features
• User-defined GPIOs (each configured to either input or output)
• Each GPIO controlled independently
• Each I/O configurable to output bit from GPIO_OUT
• Storing device-specific calibration data and hardware information like
MAC/BD address, WLAN, and Bluetooth parameter
• Programmed during production process of device
• Device performs calibration when it is powered up
