The ANALOG port provides access to the Port AD0 and
Port AD1 Analog-to-Digital input lines.
PAD0 – PAD15 HC12 Port AD0-15 is an input port or
AN0 - AN15 A/D Converter inputs.
VRH / VRL HC12 A/D Converter Reference Pins. See
HCS12 A/D User guide. To provide an external reference
voltage, R3 and R4 need to be removed to apply external
VRH or VRL respectfully. See schematic.
The BUS_PORT supports off-board memory devices
while the HCS12 is in expanded mode.
PA0/D8 - PA7/D15 High Byte Data Bus in Wide
Expanded Mode. Port A in Single Chip Mode.
A0 – A15 Latched Memory Addresses 0 to 15.
OE* Memory Output Enable signal, Active Low. Valid
with ECLK and R/W high.
WE* Memory Write Enable signal, Active Low. Valid
with ECLK high and R/W low.
RESET* HCS12 active low RESET signal.
