  • Page 3: Introduction

    Introduction Overview The series of BLE devices discussed in this guide are Holtek’s fully integrated single chip Bluetooth Low Energy transparent transmission controllers. The devices require a patch code to activate the BLE function for full BLE optimization. This patch code can be downloaded from an EEPROM or MCU for which the patch source can be selected by the IIC_SDA line status during the reset period.

The SPI-UR_N pin status will be checked after a reset after which the interface selected can be determined. If the SPI- UR_N pin status is high the SPI interface will be selected while the UART interface will be selected if the SPI-UR_N pin status is low.
