Shadow Space: Areas 0 and 2–6 are decoded by physical addresses A28–A26, which correspond
to areas 000 to 110. Address bits 31–29 are ignored. This means that the range of area 0 addresses,
for example, is H'00000000 to H'03FFFFFF, and its corresponding shadow space is the address
space obtained by adding to it H'20000000

 n (n 

=

 1–6). The address range for area 7, which is

on-chip I/O space, is H'1C000000 to H'1FFFFFFF. The address space H'1C000000 + H'20000000

 n–H'1FFFFFFF + H'20000000

 n (n

 0–7) corresponding to the area 7 shadow space is

reserved, and must not be used.

The SH7709S supports PCMCIA standard interface specifications in physical space areas 5 and 6.

The interfaces supported are basically the “IC memory card interface” and “I/O card interface”
stipulated in JEIDA Specifications Ver. 4.2 (PCMCIA2.1).
