MUTE
Address: 0x14
Type: R/W
Software Reset: 0x00
Hardware Reset: 0x00
X = don’t care; 0 = normal operation; 1 = mute
The MUTE command is handled according to the
state of the decoder, as described in section 2.5.
MUTE sets the clock running.

Hardware Reset: 0x00
X = don’t care;
0 = normal operation;
1 = write into I
The INTERRUPT is used to give STA013 the
command to write into the I2C/Ancillary Data
Buffer (Registers: 0x59 ... 0x5D). Every time the
Master has to extract the new buffer content (5
bytes) it writes into this register, setting it to a
non-zero value.
mode.
The buffered Output Clock has the same fre-
quency than the input clock (XTI)
