etc/bluetooth/hcid.conf: HCI daemon configuration file used by hcid that specifies link mode (master or slave), link policy, inquiry and scan mode, and so on

In the design of column readout stage, master and slaver structure has been adapted, where master amplifier converts charge to voltage, and slave amplifier works with standby mode to drive output bus.

It is shown by theory and case study that the master - slave clock mode in a com munication system is ideal for proper functions of the current differential protection.
