X96010
I2DS: CURRENT GENERATOR 2 DIRECTION SELECT BIT
(NON-VOLATILE)
The I2DS bit sets the polarity of Current Generator 2,
DAC2. When this bit is set to “0” (default), the Current
Generator 2 of the X96010 is configured as a Current
Source. Current Generator 2 is configured as a Cur-
rent Sink when the I2DS bit is set to “1”. See Figure 7.
Control Register 1
This register is accessed by performing a Read or Write
operation to address 81h of memory. This byte’s volatility
is determined by bit NV1234 in Control register 0.
L1DA5 - L1DA0: LUT1 DIRECT ACCESS BITS
When bit L1DAS (bit 4 in Control register 5) is set to
“1”, LUT1 is addressed by these six bits, and it is not
addressed by the output of the on-chip A/D converter.
When bit L1DAS is set to “0”, these six bits are ignored
by the X96010. See Figure 9.
A value between 00h (00₁₀) and 3Fh (63₁₀) may be writ-
ten to these register bits, to select the corresponding row
in LUT1. The written value is added to the base address
of LUT1 (90h).
Control Register 2
This register is accessed by performing a read or write
operation to address 82h of memory. This byte’s vola-
tility is determined by bit NV1234 in Control register 0.
L2DA5 - L2DA0: LUT2 DIRECT ACCESS BITS
When bit L2DAS (bit 6 in Control register 5) is set to
“1”, LUT2 is addressed by these six bits, and it is not
addressed by the output of the on-chip A/D converter.
When bit L2DAS is set to “0”, these six bits are ignored
by the X96010. See Figure 9.
A value between 00h (00₁₀) and 3Fh (63₁₀) may be writ-
ten to these register bits, to select the corresponding row
in LUT2. The written value is added to the base address
of LUT2 (D0h).
Control Register 3
This register is accessed by performing a Read or Write
operation to address 83h of memory. This byte’s volatility
is determined by bit NV1234 in Control register 0.
D1DA7 - D1DA0: D/A 1 DIRECT ACCESS BITS
When bit D1DAS (bit 5 in Control register 5) is set to
“1”, the input to the D/A converter 1 is the content of
bits D1DA7 - D1DA0, and it is not a row of LUT1.
When bit D1DAS is set to “0” (default) these eight bits
are ignored by the X96010. See Figure 8.
Control Register 4
This register is accessed by performing a Read or Write
operation to address 84h of memory. This byte’s volatil-
ity is determined by bit NV1234 in Control register 0.
D2DA7 - D2DA0: D/A 2 DIRECT ACCESS BITS
When bit D2DAS (bit 7 in Control register 5) is set to
“1”, the input to the D/A converter 1 is the content of
bits D2DA7 - D2DA0, and it is not a row of LUT2.
When bit D2DAS is set to “0” (default) these eight bits
are ignored by the X96010. (See Figure 8).
Control Register 5
This register is accessed by performing a Read or
Write operation to address 85h of memory.
L1DAS: LUT1 DIRECT ACCESS SELECT BIT (NON-
VOLATILE)
When bit L1DAS is set to “0” (default), LUT1 is
addressed by the output of the on-chip A/D converter.
When bit L1DAS is set to “1”, LUT1 is addressed by
bits L1DA5 - L1DA0.
D1DAS: D/A 1 DIRECT ACCESS SELECT BIT (NON-
VOLATILE)
When bit D1DAS is set to “0” (default), the input to the
D/A converter 1 is a row of LUT1. When bit D1DAS is set
to “1”, that input is the content of the Control register 3.
