Description
These unused bits will always be zero.
F0 is a square wave at the exact fundamental input frequency.
Normally zero. Becomes one when VB remains below SAG_THR for SAG_CNT
samples. Will not return to zero until VB rises above SAG_THR .
Normally zero. Becomes one when VA remains below SAG_THR for SAG_CNT
samples. Will not return to zero until VA rises above SAG_THR .
These unused bits will always be zero.
The CE is initialized by the MPU using CECONFIG ( CESTATE. ). This register contains in packed form SAG_CNT,
FREQSEL , EXT_PULSE , I0_SHUNT , I1_SHUNT , PULSE_SLOW , and PULSE_FAST .

Description
See description of CECONFIG below
The significance of the bits in CECONFIG is shown in the table below:
IA_SHUNT and/or IB_SHUNT can configure their respective current inputs to accept shunt resistor sensors. In this
case the CE provides an additional gain of 8 to the selected current input. WRATE may need to be adjusted based on
the values of IA_ SHUNT and IB_ SHUNT . Whenever IA_SHUNT or IB_SHUNT are set to 1, In_8 (in the equation for Kh)
is assigned a value of 8.
The CE pulse generator can be controlled by either the MPU (external) or CE (internal) variables. Control is by the
MPU if EXT_PULSE = 1. In this case, the MPU controls the pulse rate by placing values into APULSEW and APULSER .
By setting EXT_PULSE = 0, the CE controls the pulse rate based on W0SUM_X + W1SUM_X (and VAR0SUM_X +
VAR1SUM_X ).
If EXT_PULSE is 1, and if EQU = 2, the pulse inputs are W0SUM_X+W1SUM_X and VAR0SUM_X+VAR1SUM_X . In this
case, creep cannot be controlled since creep is an MPU function. If EXT_PULSE = 1 and EQU = 0, the pulse inputs
are W0SUM_X if I0SQSUM_X > I1SQSUM_X , and W1SUM_X , if I1SQSUM_X > I0SQSUM_X .
Note: The 6521 Demo Code creep function halts both internal and external pulse generation.
