Description
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.
Serial data input/output, connect to W55FXX. The pin is latched by
CLKOUT and ADDR acted as speech data and address respectively.
General purpose I/O function. If pin 9 (SPEECH_SEL) is trapped to high
at VSB power on, this function will be active.
Output clock numbers of this pin decide which mode is selected.
Connect to W55FXX.
General purpose I/O function. If pin 9 (SPEECH_SEL) is trapped to high
at VSB power on, this function will be active.
Output mode signal to W55FXX serial Flash.
