MII Management Interface (0x0510:0x0515)
Slave Controller – Register Description II-53
Table 76: Register MII Management PDI Access State (0x0517)
ESC20 ET1100 ET1200 IP Core
V2.0.0/
V2.00a
Bit Description ECAT PDI Reset Value
0 Access to MII management:
0:
ECAT has access to MII management
1: PDI has access to MII management
r/- r/(w) 0
1 Force PDI Access State:
0:
Do not change Bit 517.0
1: Reset Bit 517.0 to 0
r/w r/- 0
7:2 Reserved, write 0 r/- r/- 0
NOTE: r/ (w): assigning access to PDI (bit 0 = 1) is only possible if 0x0516.0=0 and 0x0517.1=0, and if the SII
EEPROM is loaded (0x0110[0]=1).
