GENERAL DESCRIPTION
The Z86KXX Keyboard Controllers are full-featured mem-
bers of the Z8® MCU family offering a unique register-to-
register architecture that avoids accumulator bottlenecks
and is more code efficient than RISC processors.
For keyboard applications demanding powerful I/O capa-
bilities, the Z86KXX provides 32 pins dedicated to input
and output for row, column, clock, data, and LEDs.
The on-chip counter/timer is available to relieve the system
of administering real-time tasks.
Five different internal or external interrupt sources are
maskable and prioritized in which a vectored address is
provided for efficient interrupt subroutine handling and
multitasking functions.
The Z86K15 achieves low EMI by means of several modi-
fications in the output drivers and clock circuitry of the de-
vice.
