The rising edge of the signals STD, RXWRD, TXWRD, TXCOL and SATINT activates the interrupt line XINT. If the
signal(s) changes when register 10HEX or one of the other registers is read, the interrupt line will be activated right
after the register read. Reading this register sets the interrupt line inactive. If a new interrupt is generated during
register read , the interrupt line will be activated again right after register is read.
