1.2 PIN DESCRIPTION
VDD and VSS. Power is supplied to the MCU using
these two pins. VDD is power and VSS is the
ground connection.
OSCin, OSCout. These pins are internally con-
nected to the on-chip oscillator circuit. A quartz
crystal or a ceramic resonator can be connected
between these two pins in order to allow the cor-
rect operation of the MCU with various stability/
cost trade-offs. The OSCin pin is the input pin, the
OSCout pin is the output pin.
RESET. The active low RESET pin is used to start
the microcontroller to the beginning of its program.
Additionally the quartz crystal oscillator will be dis-
abled when the RESET pin is low to reduce power
consumption during reset phase.
TEST/VPP. The TEST pin must be held at VSS for
normal operation.
If this pin is connected to a +12.5V level during the
reset phase, the EPROM programming mode is
entered.
PA0-PA7. These 8 lines are organized as one I/O
port (A). Each line may be configured as either an
input with or without pull-up resistor or as an out-
put under software control of the data direction
register. Pins PA4 to PA7 are configured as open-
drain outputs (12V drive). On PA4-PA7 pins the in-
put pull-up option is not available while PA6 and
PA7 have additional current driving capability
(25mA, VOL:1V). PA0 to PA3 pins are configured
as push-pull.
PB0-PB2, PB4-PB6. These 6 lines are organized
as one I/O port (B). Each line may be configured
as either an input with or without internal pull-up
resistor or as an output under software control of
the data direction register.
PC0-PC7. These 8 lines are organized as one I/O
port (C). Each line may be configured as either an
input with or without internal pull-up resistor or as
an output under software control of the data direc-
tion register. Pins PC0 to PC3 are configured as
open-drain (5V drive) in output mode while PC4 to
PC7 are open-drain with 12V drive and the input
pull-up options does not exist on these four pins.
PC0, PC1 and PC3 lines when in output mode are
“ANDed” with the SPI control signals and are all
open-drain. PC0 is connected to the SPI clock sig-
nal (SCL), PC1 with the SPI data signal (SDA)
while PC3 is connected with SPI enable signal
(SEN, used in S-BUS protocol). Pin PC4 and PC6
can also be inputs to software programmable edge
sensitive latches which can generate interrupts;
PC4 can be connected to Power Interrupt while
PC6 can be connected to the IRIN/NMI interrupt
line.
DA0-DA5. These pins are the six PWM D/A out-
puts of the 6-bit on-chip D/A converters. These
lines have open-drain outputs with 12V drive. The
output repetition rate is 31.25KHz (with 8MHz
clock).
AFC. This is the input of the on-chip 10 levels
comparator that can be used to implement the
AFC function. This pin is an high impedance input
able to withstand signals with a peak amplitude up
to 12V.
OSDOSCin, OSDOSCout. These are the On
Screen Display oscillator terminals. An oscillation
capacitor and coil network have to be connected to
provide the right signal to the OSD.
HSYNC, VSYNC. These are the horizontal and
vertical synchronization pins. The active polarity of
these pins to the OSD macrocell can be selected
by the user as ROM mask option. If the device is
specified to have negative logic inputs, then these
signals are low the OSD oscillator stops. If the de-
vice is specified to have positive logic inputs, then
when these signals are high the OSD oscillator
stops. VSYNC is also con-nected to the VSYNC
interrupt.
R, G, B, BLANK. Outputs from the OSD. R, G and
B are the color outputs while BLANK is the blank-
ing output. All outputs are push-pull. The active
polarity of these pins can be selected by the user
as ROM mask option.
VS. This is the output pin of the on-chip 14-bit volt-
age synthesis tuning cell (VS). The tuning signal
present at this pin gives an approximate resolution
of 40KHz per step over the UHF band. This line is
a push-pull output with standard drive.
