(1) Register setting procedure
Caution After setting the MIICTL register, set the FIFO controller control register (MFFCONT). For details,
(2) MIICTL: Ethernet control register
Bit
To update the values of the control registers, make sure that transmission and reception of frames and DMA
are stopped.
If these registers are updated while frames are being transmitted and received, or while DMA is in progress,
the operation is not guaranteed.
When using the Ethernet controller, the Ethernet control register (MIICTL) must be set in order to enable
operation of the used ports.
Access
