PRELIMINARY
GENERAL DESCRIPTION (Continued)
Z86E61/E63 Z8® MCU
WITH 16K/32K EPROM
There are three basic address spaces available to support
this configuration: Program Memory, Data Memory, and
236 general-purpose registers.
To unburden the system from coping with real-time tasks
such as counting/timing and serial data communication,
the Z86E61/E63 offers two on-chip counter/timers with a
large number of user selectable modes (Figure 1).
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
