Section 29

PC Card Controller (PCC)

The PC card controller (PCC) controls the external buffer, interrupts, and exclusive ports of the

PC card interface to be connected to this LSI. Using the PCC enables two slots of PC cards that

conform to the PCMCIA Rev. 2.1/JEIDA Ver. 4.2 standard to be easily connected to this LSI.

29.1

Features

• As a PC card interface to be connected to physical area 6, an IC memory card interface and an

I/O card interface are supported.

• Outputs control signals for the external buffer (PCC_DRV).

• Supports a preemptive operating system by switching attribute memory, common memory, and

I/O space by using addresses.

• Provides a segment bit (an address bit for the PC card) for common memory, enabling access

to a 64-Mbyte space fully conforming to PCMCIA specifications.

• Disables the PCC operation and supports only a bus interface of a PC card interface (by using

the P0USE bit of PCC0GCR).
