Field Description
0–11
CFS n _T1
[0:1]
CFIFO status at transfer to ADC n command buffer . Indicates the CFIFO n status at the time a command transfer to
ADC n command buffer is initiated. CFS n _T1 is a copy of the corresponding CFS n in EQADC_CFSR (see
Section 18.3.2.11, “eQADC CFIFO Status Register (EQADC_CFSR) ”) captured at the time a command transfer to
buffer n is initiated.
12–16 Reserved.
17–20
LCFT1
[0:3]
Last CFIFO to transfer to ADC n command buffer . Holds the CFIFO number of last CFIFO to have initiated a
command transfer to ADC n command buffer. LCFT1 has the following values:
21–31
TC_LCFT
1
[0:10]
Transfer counter for last CFIFO to transfer commands to ADC n command buffer. Indicates the number of commands
which have been completely transferred from CFIFO n when a command transfer from CFIFO n to ADC n command
buffer is initiated. TC_LCFT1 is a copy of the corresponding TC_CF n in EQADC_CFTCRn (see Section 18.3.2.9,
“eQADC CFIFO Transfer Counter Registers 0–5 (EQADC_CFTCRn) ”) captured at the time a command transfer
from CFIFO n to ADC n command buffer is initiated. This field has no meaning when LCFT1 is 0b1111.
LCFT 1 [0:3] LCFT 1 Meaning
0b0000 Last command was transferred from CFIFO0
0b0001 Last command was transferred from CFIFO1
0b0010 Last command was transferred from CFIFO2
0b0011 Last command was transferred from CFIFO3
0b0100 Last command was transferred from CFIFO4
0b0101 Last command was transferred from CFIFO5
0b0110–0b1110 Reserved
0b1111 No command was transferred to ADC n command buffer
