6.6.3 EtherCAT Reset Register (CATRESET)
CATRESET controls the reset operation of EtherCAT. EtherCAT is at the reset state when the R-IN32M3 is started.
Release the reset by this register after the completion of shared port setting for EtherCAT. In addition, reset EtherCAT
again by this register when the reset interrupt occurs from EtherCAT.
This register can be read/written in 32-bit or 16bit units.
Cautions 1. This register can be written only when releasing protection by the specific sequence with
the system protect command register (SYSPCMD). Refer to the system protect command
register (SYSPCMD) for protection releasing procedure. In addition, the special sequence
is not necessary for reading the value from this register. For details on the system
protect command register (SYSPCMD), see the R-IN32M3 Series User's Manual
(Peripheral Modules).
2. Control this register after securing the time to satisfy reset width to EtherPHY by
software in case of resetting EtherCAT. For detail, see section 6.22, Reset Circuit .
