GENERAL DESCRIPTION (Continued)
Z86C61/62/96
CMOS Z8 Microcontroller
To unburden the program from coping with the real-time
tasks, such as counting/timing and serial data communica-
tion, the Z86C61/62/96 offers two on-chip counter/timers
with a large number of user selectable modes, and an on-
board UART (Figures 1, 2, and 3).
Notes: All Signals with a preceding front slash, "/", are ac-
tive Low. For example B//W (WORD is active Low); /B/W
(BYTE is active Low, only).
