The SCL (serial clock) and SDA (serial data) signals implement a two-wire serial I
Active LOW asynchronous reset for all digital logic. Either connect this pin to V
power-on reset or apply a minimum of 10 s LOW pulse for hardware reset.
The INT_N (interrupt) pin is asserted while an interrupt condition exists. It is de-asserted
when the Interrupt Latch register is cleared. The INT_N pin is open-drain, and, therefore,
can be connected using a wired-AND with other interrupt signals.
Pin OE_N/INT_N is normally an input to the ISP1301.
When bit TRANSP_EN = 0 and bit UART_EN = 0, the OE_N/INT_N pin controls the
direction of DAT/VP, SE0/VM, DP and DM as indicated in
When suspended (either pin SUSPEND = HIGH or bit SUSPEND_REG = 1) and bit
OE_INT_EN = 1, pin OE_N/INT_N becomes a push-pull output (active LOW) to indicate
the interrupt condition.
The ISP1301 transmits USB data on the USB line under the following conditions:
