System Control
Register 108: Device Capabilities 1 (DC1), offset 0x010
This register is predefined by the part and can be used to verify features. If any bit is clear in this
register, the module is not present. The corresponding bit in the RCGC0, SCGC0, DCGC0, and the
peripheral-specific RCGC, SCGC, and DCGC registers cannot be set.
Important: This register is provided for legacy software support only.
The Peripheral Present registers should be used to determine which modules are
implemented on this microcontroller. A read of DC1 correctly identifies if a legacy module
is present but software must use the Peripheral Present registers to determine if a
module is present that is not supported by the DCn registers.
Likewise, the ADC Peripheral Properties (ADCPP) register should be used to determine
the maximum ADC sample rate and whether the temperature sensor is present. However,
to support legacy software, the MAXADCnSPD fields and the TEMPSNS bit are available.
A read of DC1 correctly identifies the maximum ADC sample rate for legacy rates and
whether the temperature sensor is present.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Watchdog Timer1 Present
When set, indicates that watchdog timer 1 is present.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
CAN Module 1 Present
When set, indicates that CAN unit 1 is present.
CAN Module 0 Present
When set, indicates that CAN unit 0 is present.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PWM Module 1 Present
When set, indicates that the PWM module is present.
