TV/VCR enable:
0 = Disabled (default)
1 = Enabled
Interrupt enable register B is used by the external processor to mask unnecessary interrupt sources for interrupt B.
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 external pin it does not affect the bits in the interrupt status register.
A given condition can set the appropriate bit in the status register and not cause an interrupt on the external pin. To
determine if this device is driving the interrupt pin either AND interrupt status register B with interrupt enable register
B or check the state of interrupt B in the interrupt B active register.

Interrupt polarity B
Interrupt polarity B:
0 = Interrupt B is active low (default).
1 = Interrupt B is active high.
Interrupt polarity B must be same as interrupt polarity A bit at bit 0 of interrupt configuration register A at address C2h.
Interrupt configuration register B is used to configure the polarity of interrupt B on the external interrupt pin. Note that
when the interrupt B is configured for active low, the pin will be driven low when active and high-impedance when
inactive (open-collector). Conversely, when the interrupt B is configured for active high, it will be driven
high-impedance for active and driven low for inactive.
