With this option enabled, EC will send IRQ12 signal to host when the
KBC mouse output buffer is full.
# On IT8xxx2 series, this configuration option has limitation:
# Port 80 and 81 I/O cycles share the same interrupt source and there is no
# status bit to indicate which cycle triggered the interrupt and data registers
# of these two ports are read only. Hence EC have to read these two data
# registers at the same time in the ISR.
# It means that the Host must alwasy write 2 bytes of data to port 80 otherwise
# port 81 data will not be updated.

help
With this option enabled, EC will accept 0x81 I/O cycle from the Host.
This allows EC to accept 2 bytes of port 80 data written from the Host.
(e.g. using iotools: iotools io_write16 0x80 0x1234)
