Interrupt Mask register for Alarm (AMASK)
Addr=23h; Reset Value=11b
MCF=1: The corresponding alarm bit (CKF) doesn’t generate interrupt.
MCF=0: The corresponding alarm bit (CKF) generates interrupt.
Pin-strap value (value=00h):
Loopback register (LOOPB)
Addr=24h; Reset Value=00h
DL3..0=0: Normal Operation
DL3..0=1: Codec #3..0 is set in Digital Loopback mode, this means that the receive PCM
signal applied to the programmed Receive Time Slot is transferred to the programmed
Transmit Time Slot.
AL3..0=0: Normal Operation
AL3..0=1: Codec #3..0 is set in Analog Loopback mode, this means that the VFRO signal is
transferred to the VFXI input internally into the Codec.
When loopbacks are enabled the signal appears also at the corresponding VFRO output. It
is possible to have no signal on the VFRO output programming the GR register to 00h in
case of digital loopback.
Pin-strap value (value=00h):
Transmit Preamplifier Gain register (TXG)
Addr=25h; Reset Value=X0h
