The interrupt enable register A is used by the host processor to mask unnecessary interrupt sources. Bits loaded with
a 1 allow the corresponding interrupt condition to generate an interrupt on the external pin. Conversely, bits loaded
with a 0 mask the corresponding interrupt condition from generating an interrupt on the external pin. Note this register
only affects the interrupt on the external terminal, it does not affect the bits in interrupt status register A. A given
condition can set the appropriate bit in the status register and not cause an interrupt on the external terminal. To
determine if this device is driving the interrupt terminal either perform a logical AND of interrupt status register A with
interrupt enable register A, or check the state of the interrupt A bit in the interrupt configuration register at address
C2h.
Lock interrupt enable:
0 = Disabled (default)
1 = Enabled
Cycle complete interrupt enable:
0 = Disabled (default)
1 = Enabled
Bus error interrupt enable:
0 = Disabled (default)
1 = Enabled
FIFO threshold interrupt enable:
0 = Disabled (default)
1 = Enabled
Line interrupt enable:
0 = Disabled (default)
1 = Enabled
Data interrupt enable:
0 = Disabled (default)
1 = Enabled
