WF_CAP_EN

When this bit is set, a waveform capture is started. 0x0

R/W

0 The waveform capture is disabled. The waveform

buffer contents are maintained.

1 The waveform capture is started, according to the

type of capture in WF_CAP_SEL and the WF_SRC

bits when this bit goes from a 0 to a 1.

[3:0]

Selects which data to read out of the waveform

buffer through SPI.

1011 VB.

1100 IC.

1101 VC.

1110 IN if WF_IN_EN = 1 in the WFB_CFG register.

1111 Single address read (SPI burst read mode is

disabled).

WFB_TRIG_ADDR

This holds the address of the last sample put into

the waveform buffer after a trigger event occurred,

which is within a sample or two of when the actual

trigger event occurred.

0x0

UPERIOD_SEL

Set this bit to use a user configured line period, in

USER_PERIOD, for the resampling calculation. If

this bit is clear, the phase voltage line period

selected by the LP_SEL[1:0] bits in the ZX_LP_SEL

0x0
