TIMING REGISTER
TR (TR00–TR07)
(Address (SR4–SR0) = 0AH)
Figure 29 shows the various operations under the control of the
Timing Register.
TR BIT DESCRIPTION
Crystal Oscillator Circuit (TR00)
If this bit is set to “0,” the internal oscillator circuit will be
disabled. Disabling the oscillator circuit is possible when an
external clock module is used, thus, saving power.
ADC Bias Currents (TR01)
If this bit is set to “1,” all analog bias currents will be doubled.
Duty Cycle Equalizer (TR03)
When this bit is set to “1,” the clock duty cycle equalizer circuit
is active. This will only have an effect on the ADC operation.
The digital core clock will not be affected.
Clock Delay (TR05–TR06)
Using these two bits, it is possible to insert a delay in the clock
signal to the digital core. These bits control the insertion of
the delay.
Reserved (TR02, TR04, TR07)
Zero must be written to the bits in these registers.

VREF ADJUST REGISTER
VR (VR00–VR07)
(Address (SR4–SR0) = 0AH)
Figure 30 shows the various operations under the control of the
VREF Adjust Register.
VR BIT DESCRIPTION
Reserved (VR00)
This register is reserved and “1” must be written to this bit.
Reserved (VR01–VR03)
Zero must be written to these registers.
Reference Voltage Adjust (VR04–VR06)
By setting the value of this 3-bit word, it is possible to trim the
ADC internal voltage reference VREFADC.
