These peak detector registers allow the user to monitor the receive out signal (Rout) peak level at reference point R3 (see

Figure #1). The information is in 16-bit 2âs complement linear coded format presented in two 8 bit registers. The high byte

is in Register 2 and the low byte is in Register 1.
