Description
0x28
PULSE_SLOW
1
When PULSE_SLOW > 0, the pulse generator input is reduced 64x.
When PULSE_FAST > 0, the pulse generator input is increased 16x.
These two parameters control the pulse gain factor X (see table below).
Allowed values are either 1 or –1.

WRATE

Kh =
VMAX*IMAX*47.1132 / (In_8*WRATE*NACC*X) Wh/pulse (for MUX_DIV = 1).
VMAX*IMAX*36.2409 / (In_8*WRATE*NACC*X) Wh/pulse (for MUX_DIV = 2).
0x36
SUM_PRE
2520
PRE_SAMPS * SUM_CYCLES. This variable is also called NACC.
0x37
EXT_PULSE
15
Should be 15 or 0. When zero, causes the pulse generators to respond to
WSUM_X and VARSUM_X. Otherwise, the generators respond to values the
MPU places in APULSEW and APULSER.
0x3C
PULSE_WIDTH
50
The maximum pulse width (low-going pulse) is:
(2 * PULSE_WIDTH + 1) * 397s (for MUX_DIV = 1)
(2 * PULSE_WIDTH + 1) * 305s (for MUX_DIV = 2)
0 is a legitimate value.
0x26
APULSEW
0
Wh pulse generator input, to be updated by the MPU when using external pulse
generation (see DIO_PW bit). The output pulse rate is:
APULSEW * FS * 2
-32 * WRATE * 2-14
This input is buffered and can be updated by the MPU during a computation in-
terval. The change will take effect at the beginning of the next interval.
0x27
APULSER
0
VARh pulse generator input to be updated by the MPU when using external
pulse generation (see DIO_PV bit). The output pulse rate is:
APULSER * FS*2
-32 * WRATE * 2-14
This input is buffered and can be updated by the MPU during a computation in-
terval. The change will take effect at the beginning of the next interval.
