Misc Control 2
Bit 0 — Bypass Frequency Synthesizer
This bit determines internal time base.
Bit 1 — Low-Power Dynamic Mode
This bit determines whether Low-Power Dynamic mode is enabled. For maximum operational
power savings, keep this bit set to ‘1’.
Bit 2 — Suspend
This bit enables Suspend mode. After entering Suspend, AEN should be pulled high for lowest
power consumption. When this bit is high and AEN is high, all ISA bus interface inputs are turned
off. In 82386SL systems when the processor is in Suspend mode, the ISA bus interface signals
float; this feature will prevent high current flow in the CL-PD67XX inputs.
Bit 3 — 5V Core
This bit selects input threshold circuits for use when 3.3 or 5.0 volts is connected to the
CL-PD67XX CORE_VDD pins. This bit must be set to ‘0’ when the CORE_VDD pins are connect-
ed to 3.3 volts to preserve TTL-compatible input thresholds to the card socket.
Bit 4 — Drive LED Enable
NOTE:
This bit should be set to ‘0’ if in Memory Card Interface mode.
This bit determines whether -SPKR is used to drive an LED on the IRQ12 (see
page 14
) for disk
drives.

Normal operation, internal clock = CLK input frequency x 7/4.
Internal clock = CLK input frequency (see
page 15
).

Clock runs always.
Normal operation, stop clock when possible.

Normal operation.
Stop Frequency Synthesizer, enable all Low-Power modes and disable socket access.

Normal operation: use when CORE_VDD pin is connected to 3.3 volts.
Selects input thresholds for use when 5.0 volts is connected to the CL-PD67XX CORE_VDD pins.

IRQ12 operates normally.
IRQ12 becomes an open-drain output suitable for driving an LED (driven whenever the card -SPKR
output is turned on, and the corresponding Speaker Is LED input bit (see page
64
) is set).
