Note: As accesses to this register become unavailable when the clock (= CLK_U) supply from PHY is stopped with
6. DMACRDREQ (DMAC Read Request register)
Symbol
The bit for requesting read access to the DMAC registers. Setting this bit to 1 will make a
read access to the address specified by dmardadr. When the read access is complete and
the read value is stored in the DMAC Read Value register, this bit will be automatically
cleared and the int_dmac_reg_rd bit of Interrupt Status register will be set to 1.
0y0: No operation
0y1: Issue read request
The bit for forcibly clearing the register read access request associated with DMAC.
Setting this bit to 1 will forcibly stop the register read access request by dmardreq and the
value of dmardreq will be cleared to 0. After the forced clearing completes, this bit will be
automatically cleared.
0y0: No operation
0y1: Issue forced clearing
Bit
UDC2 suspended, no access should be made. If this register is accessed when the phy_suspend bit of Power
