79 / 204 page  TMC8462 Datasheet • Document Revision V1.4 • 2018-May -09 79 / 204 Bit Description ECAT PDI Reset Value 14 Error Write Enable∗2: 0: No error 1: Write Command without Write enable r/- r/- 15 Busy: 0: EEPROM Interface is idle 1: EEPROM Interface is busy r/- r/- Table 59: Register 0x0502:0x0503 (PROM Cntrl) Note r/(w): write access depends upon the assignment of the EEPROM interface (ECAT/PDI). Write access is generally blocked if EEPROM interface is busy (0x0502.15=1). Note r/[w]: EEPROM emulation only: write access is possible if EEPROM interface is busy (0x0502.15=1). PDI acknowledges pending commands by writing a 1 into the corresponding command register bits (0x0502.10:8). Errors can be indicated by writing a 1 into the error bit 0x0502.13. Acknowledging clears AL Event Request 0x0220.5. *1 Write Enable bit 0 is self-clearing at the SOF of the next frame, Command bits [10:8] are self-clearing after the command is executed (EEPROM Busy ends). Writing "‘000"’ to the command register will also clear the error bits [14:13]. Command bits [10:8] are ignored if Error Acknowledge/Command is pending (bit 13). *2 Error bits are cleared by writing "‘000"’ (or any valid command) to Command Register Bits [10:8]. 6.4.10.4 EEPROM Address (0x0504:0x0507) Bit Description ECAT PDI Reset Value 31:0 EEPROM Address 0: First word (= 16 bit) 1: Second word . . . Actually used EEPROM Address bits: [9:0]: EEPROM size up to 16 kBit [17:0]: EEPROM size 32 kBit . . . 4 Mbit [32:0]: EEPROM Emulation r/(w) r/(w) Table 60: Register 0x0504:0x0507 (PROM Address) Note r/(w): write access depends upon the assignment of the EEPROM interface (ECAT/PDI). Write access is generally blocked if EEPROM interface is busy (0x0502.15=1). ©2018 TRINAMIC Motion Control GmbH & Co. KG, Hamburg, Germany Terms of delivery and rights to technical change reserved.
