ple rate) if the signal does not encounter a zero crossing. The zero cross function is independently mon-

When this bit is set, the output of the DAC is inverted.
6.13 Status - Address 0Dh
For all bits in this register, a ‘1’ means the associated condition has occurred at least once since the register
was last read. A ‘0’ means the associated condition has NOT occurred since the last reading of the register.
Status bits that are masked off in the associated mask register will always be ‘0’ in this register. This register
defaults to 00h.
6.13.1 E to F C-Buffer Transfer
Function:
Indicates the completion of an E to F C-buffer transfer. See “Channel Status Buffer Management” on
page 53 for more information.
