User Accessible Registers (Base = 0x1830_0000)
This section describes the registers in the Clock Module. The address value on the table shows the
relative address in hexadecimal. The width describes the number of bits in the register. The access
field specifies the valid access type for the register, where ‘RW’ stands for read and writes access,
and ‘RO’ for read only access, respectively. ‘C’ following ‘RW’ or ‘RO’ means the corresponding
bit is cleared after writing “1” in the matching position.
