Section 10 PC Card Controller (PCC)
10.1
Overview
The PC Card Controller (PCC) controls the internal buffers, interrupts, and PCMCIA-defined ports
of the PC card interfaces, which should be connected to the Intelligent Peripheral Controller (IPC).
The PCC enables two slots of the PC cards that are compliant with the specifications PCMCIA
Rev. 2.1/JEIDA Version 4.2, thereby ensuring a smooth connection to the IPC.
10.2
Features
•
Two slots of the PC card interfaces can be simultaneously controlled
•
Supports IC memory card interface, and I/O and Memory card interface, which function as PC
card interfaces and are connected to physical areas 5 and 6. Area 6, which is referred as channel
0 (PCC0), supports both of the IC memory card interface, and I/O & Memory card interface.
Area 5, which is referred as channel1 (PCC1), supports both of the IC memory card interface,
and I/O & Memory card interface.
•
Able to switch to an Attribute memory or a Common memory, or an I/O space via the CPU
addresses.
•
Provides a segment bit (an address bit for the PC card) for the Common memory; therefore, a
64-MB space of full PCMCIA specifications can be accessed.
•
Provides a flexible power switch interface to either TPS2206 or MIC2563.
