FUNCTION
I Test pad. Active high with internal pull low resistor.
ROSC
I
Connect resistor to V_DD pad to generate speech or melody playing
clock source.
PWM1/DAC
O
While speech or melody is active, PWM1/DAC is speaker direct driving
output or DAC output controlled by voice output file.
PWM2
ADDR (5)
O
While speech or melody is active, PWM2 is another speaker direct
driving output.
External serial memory address write clock for voice extension
(W536120T only). The “Tri-sate serial bus” mask option can use tri-
O sate WRP pad while external voice ROM is not available. Default that
mask option is disabled and fixes WRP pad state while external voice is
not enabled to get chip low power consumption.
CLK (5)
External serial memory address read clock for voice extension.
O (W536120T only). The pad state is same as WRP pad depended on
“Tri-sate serial bus” mask option.
DATA (5)
External serial memory data in/out for voice extension (W536120T
I/O only). The pad state is same as WRP pad depended on “Tri-sate serial
bus” mask option.

O/IO
LCD segment output pads, and can be shared as general input/output
