The ISP1504 provides an internal pull-up resistor to sense the value of the ID pin. The
pull-up resistor must first be enabled by setting the ID_PULLUP register bit to logic 1. If
the value on ID has changed, the ISP1504 will send an RXCMD or interrupt to the link by
time t
not changed.

The ISP1504 supports both 6-pin serial mode and 3-pin serial mode, controlled by
bits 6PIN_FSLS_SERIAL and 3PIN_FSLS_SERIAL of the Interface Control register. For
