TM4C1231C3PM Datasheet, PDF (402/1145 Pages) Texas Instruments – Tiva™ TM4C1231C3PM Microcontroller

System Control
Register 110: Device Capabilities 3 (DC3), offset 0x018
This register is predefined by the part and can be used to verify features. If any bit is clear in this
register, the feature is not present.
Important: This register is provided for legacy software support only.
For some modules, the peripheral-resident Peripheral Properties registers should be
used to determine which pins are available on this microcontroller. A read of DC3
correctly identifies if a legacy pin is present but software must use the Peripheral
Properties registers to determine if a pin is present that is not supported by the DCn
registers.

Description
32KHz Input Clock Available
When set, indicates an even CCP pin is present and can be used as a
32-KHz input clock.
Note: The GPTMPP register does not provide this information.
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.
T2CCP1 Pin Present
When set, indicates that Capture/Compare/PWM pin T2CCP1 is present.
Note: The GPTMPP register does not provide this information.
T2CCP0 Pin Present
When set, indicates that Capture/Compare/PWM pin T2CCP0 is present.
Note: The GPTMPP register does not provide this information.
T1CCP1 Pin Present
When set, indicates that Capture/Compare/PWM pin T1CCP1 is present.
Note: The GPTMPP register does not provide this information.
T1CCP0 Pin Present
When set, indicates that Capture/Compare/PWM pin T1CCP0 is present.
Note: The GPTMPP register does not provide this information.
