Event trapping to selection speech output sound. Default is
high edge trigger.
General purpose I/O function. If pin 9 (SPEECH_SEL) is
trapped to high at VSB power on, this function will be
active. The I/O control and status is defined in BANK0
Index 13h~14h. Otherwise, GPIO pin or PWMOUT Fan
control can be selected by registers, but the PWMOUT can
not support Smart Fan.
End of Process signal input from cascaded Flash.
General purpose I/O function pin. If pin 9 (SPEECH_SEL)
is trapped to high at VSB power on, this function will be
active.
Resistor (Rosc) connect to VSB used to adjust ring
oscillator frequency.
Speech address pulse output, connect to W55FXX. When
this pin translates from logic high to logic low, it will latch
the data pin 6 and shift it into a speech flash address
counter.
General purpose I/O function. If pin 9 (SPEECH_SEL) is
trapped to high at VSB power on, this function will be
active.
Speech clock output, for speech data read-out and write-in,
connect to W55FXX. When this pin translates from logic
high to logic low, the data pin 6 will be latched by this
clock.
General purpose I/O function. If pin 9 (SPEECH_SEL) is
trapped to high at VSB power on, this function will be
active.
