AVxx32A Series
Edege/Level; Hold/UnHold; Retrigger/Irretrigger.
□ CPU_INTERFACE mode: Addressing access mode by input pulse count. In this mode, A1~A7
(ROW1~4, COL1~3) are disable, A8 (COL4) can be access up to 32 subtables.
(6). The A8 or M16 can be selected as NORMAL, SEQUENTIAL or CPU_INTERFACE. ( Mask option )
□ NORMAL: normal mode as in item (5).
□ SEQUENTIAL: can be selected to combine with MODE input or not. ( Mask option )
(A). If A8 or M16 is in SEQUENTIAL and is combined with MODE input:
MODE=0 : the device will response by one subtable sequentially and cyclically, from subtable1 to
user defined end subtable (subtable n, n=1~16).
MODE=1 : the device will response by one subtable sequentially and cyclically, from subtable 17
to user defined end subtable (subtable n, n=17~32).
The number of subtables (used in sequence) in MODE=1 and MODE=0 must be equal; this
number must be less than 16.
(B). If A8 or M16 is in SEQUENTIAL and is not combined with MODE input:
The device will response by one subtable sequentially and cyclically, from subtable1 to user
defined end subtable (subtable n, n=1~32).
The relationship between SEQUENTIAL ( A8/M16 ) and other inputs ( A1~A7 / M1~M15 ) can be
selected as RESET or UNRESET. ( Mask option )
◎ RESET: once the other inputs are triggered, the SEQUENTIAL sequence will reset to subtable 1.
◎ UNRESET: SEQUENTIAL sequence and other inputs are independent.
(7). Four STS pins have the following options: ( Mask option )
□ OUT1: Cout (Current output) or STS1 output
□ OUT2: PWM1 or STS2 output
□ OUT3: PWM2 or STS3 output
□ MODE/STS4: MODE selection or STS4 output
Cout has 3 current output levels: 1>1.5mA ; 2>3mA ; 3>4.5mA. ( full scale ; Vdd=3V )
PWM1 and PWM2 must be selected on the same time, they can directly drive buzzer or 8, 16, 32 or 64
ohms speaker.
