ISA-to-PC-Card (PCMCIA) Controllers — PD6710/’22
9.4.0.1
23h System Memory Map 2 End Address High
2Bh System Memory Map 3 End Address High
33h System Memory Map 4 End Address High
Bits 3:0 — End Address 23:20
This field contains the most-significant four bits of the End Address. See the description of the End
Address field associated with bits 7:0 of the System Memory Map 0–4 End Address Low register
(see “System Memory Map 0–4 End Address Low” on page 66).
Bits 7:6 — Card Timer Select
00
Selects Timer Set 0.
01
Selects Timer Set 1.
10
Selects Timer Set 1.
11
Selects Timer Set 1.
This field selects the Timeset registers used to control socket timing for card accesses in this
window address range. Timeset 0 and 1 reset to values compatible with PC Card standards. The
mapping of bits 7:6 to Timeset 0 and 1, as shown in the preceding table, is done for software
compatibility with older ISA bus-based PC Card controllers that use ISA bus wait states instead of
Timeset registers (see “Setup Timing 0–1” on page 84).
