Input selector control register
The write only, two byte, input selector control register is
located on absolute address 0FFFH (4095) and consists
of 16 bits, starting with bit 0 and ending with bit 15.
Deviation from the I
2
C-bus specification
1.
The data hold time (t
HD;DAT
) for this device (
≥
0 ns as
stated in the I
2
C-bus specification) should be as
follows:
a) For the crystal oscillator mode (SHTCB = 0):

b) For the slave oscillator mode (SHTCB = 0):

c) For the slave oscillator mode (SHTCB = 1):

During the write cycle, the I
2
C-bus clock frequency must
be reduced.
The I
2
C-bus clock frequency has the following constraints:
f
s
>

×
f
IIC
f
s
= I
2
S-bus sampling frequency
f
IIC
= I
2
C-bus clock frequency.
If this constraint cannot be met, a higher I
2
C-bus frequency
can be obtained in the following way:
By making the I
2
C-bus master insert a delay (t
d
) after the
acknowledge pulse (see Fig.11). The delay should be
larger than or equal to 1/f
s
where f
s
is the I
2
S-bus
sampling frequency.
By not using the auto-increment feature. This means
that each data word must be preceded by its intended
destination address.
