FUNCTIONAL DESCRIPTION
The Z8 DTCincorporates special functions to enhance the
Z8’s versatility in consumer, industrial and television con-
trol applications.
Pulse Width Modulator
(PWM). The has seven PWM
channels (Figure 9). There are three types of PWM cir-
cuits: PWM1 (one channel of 14-bit resolution) typically
used for Voltage Synthesis Tuning, PWM8-PWM6 (three
channels of 6-bit resolution) typically used for audio level
control, and PWM9, 10, 11 (three channels of 8-bit resolu-
tion) typically used for picture level control. The PWM con-
trol registers are mapped into external memory and are ac-
cessed through LDE and LDEI instructions.
PWM1.
It is a push-pull output.
PWMs 6 through 11
. They have their maximum values
(on times) when all 1s are loaded in their PWM Value reg-
isters (and minimum value for all 0s). PWM1 has a maxi-
mum value for all 0s and minimum value for all 1s.
On-Screen Display (OSD).
The OSD has a capability of
displaying 6 rows x 20 columns of 96 kinds of characters
for high resolution (11 x 15 dots) patterns (Figures 10 and
11).
