Section 30 PC Card Controller (PCC)
Section 30 PC Card Controller (PCC)
30.1 Overview
The PC card controller (PCC) controls the external buffer, interrupts, and exclusive ports of the
PC card interface to be connected to the SH7727. 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 the
SH7727.
30.1.1 Features
The PCC has the following 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 (PCC0DRV).
• 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-MB space fully conforming to PCMCIA specifications.
• Disables the PCC operation and supports only a bus interface of a PC card interface which is
same as the SH7709/SH7729 Series (by using the P0USE bit of PCC0GCR).
• When the PCC is enabled (P0USE bit in PCC0GCR set to 1), PCC0WAIT functions as a
WAIT signal in the same manner as WAIT.
