GENERAL RELEASE SPECIFICATION
PRELMNARY
1.2.12
PWM0**-PWM7**
These pins are dedicated for 8-bit PWM channels 0 to 7, which have +5V open-drain
software options. See
SECTION 8
for a detailed description.
1.2.13
HSYNC, VSYNC
These two input pins are for video sync signals input from the host computer. The signals
will be used for video mode detection and output to
HSYNO
and
VSYNO
. The host
computer can also send a composite sync signal to the
HSYNC
input. This composite
signal will be separated internally. The polarity of the input signals can be either positive or
negative. These two pins contain internal Schmitt triggers as part of their inputs to improve
noise immunity. See
SECTION 10
for a detail description.
1.3
Options
MC68HC05BD7 provides an option for IRQ interrupt edge only sensitivity or edge and level
sensitivity and one option register for individual PWM channels 0 to 7 to be programmed
as open-drain type output. The IRQ option is selected by setting the appropriate bit in the
MFTCSR register at address $0008 and the PWM open-drain option register is located at
address $0012.
