Control Register 4
This register is accessed by performing a Read or Write
operation to address 84h of memory. This byte’s volatility 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
D2DA-D2DA0, and it is not a row of LUT2. When bit D2DAS
is set to “0” (default) these eight bits are ignored by the
X96012. See Figure 9.
Control Register 5
This register is accessed by performing a Read or Write
operation to address 85h of memory.
I1FSO1 - I1FSO0: CURRENT GENERATOR 1 FULL
SCALE OUTPUT SET BITS (NON-VOLATILE)
These two bits are used to set the full scale output current at
the Current Generator 1 pin, I1. If both bits are set to “0”
(default), an external resistor connected between pin R1 and
VSS, determines the full scale output current available at pin
I1. The other three options are indicated in Table 2. The
direction of this current is set by bit I1DS in Control register
0. See Figure 8.
I2FSO1 - I2FSO0: CURRENT GENERATOR 2 FULL
SCALE OUTPUT CURRENT SET BITS (NON-VOLATILE)
These two bits are used to set the full scale output current at
the Current Generator 2 pin, I2. If both bits are set to “0”
(default), an external resistor connected between pin R2 and
Vss, determines the full scale output current available at pin
I2. The other three options are indicated Table 3. The direction
of this current is set by bit I2DS in Control Register 0.
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.
L2DAS: LUT2 DIRECT ACCESS SELECT BIT
(NON-VOLATILE)
When bit L2DAS is set to “0” (default), LUT2 is addressed by
the output of the on-chip A/D converter. When bit L2DAS is
set to “1”, LUT2 is addressed by bits L2DA5 - L2DA0.
D2DAS: D/A 2 DIRECT ACCESS SELECT BIT
(NONVOLATILE)
When bit D2DAS is set to “0” (default), the input to the D/A
converter 2 is a row of LUT2. When bit D2DAS is set to “1”, that
input is the content of the Control register 4.
Control Register 6
This register is accessed by performing a Read or Write
operation to address 86h of memory.
WEL: WRITE ENABLE LATCH (VOLATILE)
The WEL bit controls the Write Enable status of the entire
X96012 device. This bit must be set to “1” before any other
Write operation (volatile or nonvolatile). Otherwise, any
proceeding Write operation to memory is aborted and no ACK
is issued after a Data Byte.
The WEL bit is a volatile latch that powers up in the “0” state
(disabled). The WEL bit is enabled by writing 100000002 to
Control register 6. Once enabled, the WEL bit remains set to “1”
until the X96012 is powered down, and then up again, or until it
is reset to “0” by writing 000000002 to Control register 6.
A Write operation that modifies the value of the WEL bit will not
cause a change in other bits of Control register 6.
Status Register - ADC Output
This register is accessed by performing a Read operation to
address 87h of memory.
AD7 - AD0: A/D CONVERTER OUTPUT BITS (READ
ONLY)
These eight bits are the binary output of the on-chip A/D
converter. The output is 000000002 for minimum input and
111111112 for full scale input. The six MSBs select a row of
the LUTs.
