2.13. PCMCIA Controller
HMS30C7110
The HMS30C7110® integrates a PCMCIA controller which supports 16-bits PC card and 32-bits
PC card (Cardbus) functionalities.
The PCMCIA Controller supports 1 socket 16-bits PC Card or 1 socket CardBus card.
2.13.1. User Accessible Registers (Base = 0x1940_0000)
This section describes all base, control and status register inside the PCMCIA. The address field
indicates a relative address in hexadecimal. The base address for 16-bits PC Card is 0x19400000
and the base address for CARDBUS is 0x19480000. 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.
