Reduced EMI Mode
There are two bits in the AUXR register that
can be set to reduce the internal clock drive
and disable the ALE output. AO (AUXR.0)
when set turns off the ALE output. LO
(AUXR.1) when set reduces the drive of the
internal clock circuitry. Both bits are cleared
on Reset. With LO set the 87C575 will still
operate at 12MHz, but will have reduced EMI
in the range above 100MHz.

AO:
Turns off ALE output.
LO:
Reduces drive of internal clock
circuitry. 8XC575 spec’d to 12MHz
when LO set.
INTERNAL RESET
Internal resets generated by the power on,
low voltage, and oscillator fail detect circuits
are self timed to guarantee proper
initialization of the 8XC575. Reset will be held
approximately 24 oscillator periods after
normal conditions are detected by all enabled
detect circuits. Internal resets do not drive
RST but will cause missing pulses on ALE.
