Bit
Interrupt. When unmasked (BERO
= 1), an interrupt is initiated when
the bit error counter overflows.
Interrupt vector = 00010000.
Auxiliary Pattern Interrupt. When
unmasked (AUXPI = 1), an interrupt
is initiated when the AUXP status bit
of page 03H, address 15H goes
high. Interrupt vector = 01000000.
