Note 1:
In the transmit direction the sine tone level is controlled by the DGX register and the V2F bit.
Note 2:
In the transmit direction the DTMF level is controlled by the DGX register only.
Note 3:
In the transmit direction the square tone level is controlled by the V1 register and the DGX register. Levels
exceeding 3.14 dBm0 are limited by the transmit saturation logic to 3.14 dBm0.
Note 4:
In the receive direction the sine tone level is controlled by the V2 and the AGR register.
Note 5:
In the receive direction the square tone level is controlled by the V1, V2C and the AGR register.
