19.3.2.11 eQADC CFIFO Status Register (EQADC_CFSR)
The EQADC_CFSR contains the current CFIFO status. The EQADC_CFSRs are read only. Writing to the
EQADC_CFSR has no effect.
17–20 LCFTSSI
[0:3]
Last CFIFO to transfer commands through the eQADC SSI. Holds the CFIFO number of
last CFIFO to have initiated a command transfer to an external command buffer through
the eQADC SSI. LCFTSSI does not indicate the transmission of null messages. LCFTSSI
has the following values:
21–31 TC_LCFTSS
I[0:10]
Transfer counter for last CFIFO to transfer commands through eQADC SSI. Indicates the
number of commands which have been completely transferred from a particular CFIFO at
the time a command transfer from that CFIFO to an external command buffer is initiated.
TC_LCFTSSI is a copy of the corresponding TC_CFn in EQADC_CFTCRn (see Section
19.3.2.9) captured at the time a command transfer to an external command buffer is
initiated. This field has no meaning when LCFTSSI is 0b1111.
