Function
Bus High Enable (Intel bus mode)
If 16-bit bus interface mode is enabled, this
signal indicates a data transfer on the upper
byte of the data bus (D8 … D15). In 8-bit bus
interface mode this signal has no function and
should be tied to
Bus Low Enable (Motorola bus mode)
If 16-bit bus interface mode is enabled, this
signal indicates a data transfer on the lower
byte of the data bus (D0 … D7). In 8-bit bus
interface mode this signal has no function and
should be tied to
Interrupt Request
INT serves as general interrupt request which
may include all interrupt sources. These
interrupt sources can be masked via registers
IMR0 … 5. Interrupt status is reported via
registers GIS (Global Interrupt Status) and
ISR0 … 3,5.
Output characteristics (push-pull active low/
high, open drain) are determined by
programming the IPC register.
