2.10.2. User Accessible Registers (Base = 0x1840_0000)
HMS30C7110
This section describes all base, control and status register inside SPI. The address field indicates a
relative address in hexadecimal. The base address is 0x18500000. Width specifies the number of
bits in the register and access specifies the valid access types that register. Where RW stands for
read and write access, RO for read only access. A “C” appended to RW or RO, indicates that some
or all of the bits can be cleared after a write ‘1’ in corresponding bit.
