Sixteen SIM pins can be configured for general-purpose discrete input and output. Al-
though these pins are organized into two ports, port E and port F, function assignment
is by individual pin. Pin assignment registers, data direction registers, and data regis-
ters are used to implement discrete I/O.
Bits in the port E and port F pin assignment registers (PEPAR and PFPAR) control the
functions of the pins on each port. Any bit set to one defines the corresponding pin as
a bus control signal. Any bit cleared to zero defines the corresponding pin as an I/O
pin.
Bits in the port E and port F data direction registers (DDRE and DDRF) control the
direction of the pin drivers when the pins are configured as I/O. Any bit in a register set
to one configures the corresponding pin as an output. Any bit in a register cleared to
zero configures the corresponding pin as an input. These registers can be read or
written at any time.
A write to the port E and port F data registers (PORTE[0:1] and PORTF[0:1]) is stored
in an internal data latch, and if any pin in the corresponding port is configured as an
output, the value stored for that bit is driven out on the pin. A read of a data register
returns the value at the pin only if the pin is configured as a discrete input. Otherwise,
the value read is the value stored in the port data register. Both data registers can be
accessed in two locations and can be read or written at any time.
The test submodule supports scan-based testing of the various MCU modules. It is in-
tegrated into the SIM to support production test. Test submodule registers are intend-
ed for Motorola use only. Register names and addresses are provided in D.2.2
System Integration Test Register and D.2.5 System Integration Test Register
(ECLK) to show the user that these addresses are occupied. The QUOT pin is also
used for factory test.
