The
MCU_PORT
provides access to the peripheral
features and I/O lines of the HCS12.
** Note signals with alternate connections on the
development board:
PB0 - 7 [D0 - 7] provide address / data on the
expanded HCS12.
PK0 - 5 [XA14 - XA19] provide high order paged
address lines on the expanded HCS12.
PM0 - 1 [CAN RXD0, TXD0] CAN channel 0 to CAN
Port transceiver.
PS0 - 1 [COM Port RXD0, TXD0]
PS2 - 3 [JP3 Port RXD1, TXD2]
PS4 - 7 [SPI Port] provides LCD_PORT serial
interface.

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.
