22. UDC2 (UDC2 register) (0x0200 to 0x03FC)
(0xF440_0000) + 0x200-0x3FC. AHB data bus of UDC2AB has 32 bits, of which bits 15-0
correspond with the UDC2 data bus. Bits 31-16 are reserved bits and read-only (read value: 0).
Make a WORD (32-bit) access for both write and read. (However, a BYTE (8-bit) access may be
made for Write accesses to the EPx_FIFO register. Details will be discussed later.)
UDC2). Be sure to begin subsequent accesses after the previous UDC2 register access is
completed, using the int_udc2_reg_rd interrupt. (You can also use the udc2rdreq bit of UDC2
Read Request register to confirm the access status when reading.)
The internal register of UDC2 (16 bits) can be accessed by making an access to the

and to “Reserved” registers. (In case those registers are accessed, the access from UDC2AB
to UDC2 itself will take place. It will be a Dummy write to UDC2 in case of write accesses.
In case of read accesses, the read data from UDC2 (udc2_rdata) will be an indefinite value
and the indefinite value will be set to the UDC2 Read Value register.)
the clock (= CLK_U) supply from PHY is stopped. Make no register accesses to UDC2 in
such cases. If the UDC2 register is accessed when the phy_suspend bit of Power Detect
Control register is set to 1, an AHB error will be returned.
