PDI Error Counter (0x030D)
II-42 Slave Controller – Register Description
3.36 PDI Error Counter (0x030D)
Table 53: Register PDI Error Counter (0x030D)
ESC20 ET1100 ET1200 IP Core
Bit Description ECAT PDI Reset Value
7:0 PDI Error counter (counting is stopped when
0xFF is reached). Counts if a PDI access has
an interface error. r/
w(clr) r/- 0
NOTE: Error Counter 0x030D and Error Code 0x030E are cleared if error counter 0x030D is written. Write value
is ignored (write 0).

Table 54: Register SPI PDI Error Code (0x030E)
ESC20 ET1100 ET1200 IP Core
V2.3.0/
V2.03a
Bit Description ECAT PDI Reset Value
SPI access which caused last PDI Error. r/- r/- 0
2:0 Number of SPI clock cycles of whole access
(modulo 8)
3 Busy violation during read access
4 Read termination missing
5 Access continued after read termination byte
7:6 SPI command CMD[2:1]
NOTE: Error Counter 0x030D and Error Code 0x030E are cleared if error counter 0x030D is written. Write value
is ignored (write 0).

3 Addressing error for a write access
(A[0]=1 and BHE(act. low)=0)
7:4 reserved
NOTE: Error Counter 0x030D and Error Code 0x030E are cleared if error counter 0x030D is written. Write value
is ignored (write 0).
