Line: Line number interrupt clear
0 = Disabled (default)
1 = Clear bit 0 (line interrupt available) in the interrupt status 0 register at subaddress F2h
The host interrupt clear 0 and 1 registers are used by the external processor to clear the interrupt status bits
in the host interrupt status 0 and 1 registers. When no nonmasked interrupts remain set in the registers, the
external interrupt terminal also becomes inactive.
