System Control
Register 20: 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 module is not present. The corresponding bit in the RCGC0, SCGC0, and DCGC0
registers cannot be set.

Description
32KHz Input Clock Available
When set, indicates an even CCP pin is present and can be used as a
32-KHz input clock.
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.
CCP5 Pin Present
When set, indicates that Capture/Compare/PWM pin 5 is present.
CCP4 Pin Present
When set, indicates that Capture/Compare/PWM pin 4 is present.
CCP3 Pin Present
When set, indicates that Capture/Compare/PWM pin 3 is present.
CCP2 Pin Present
When set, indicates that Capture/Compare/PWM pin 2 is present.
CCP1 Pin Present
When set, indicates that Capture/Compare/PWM pin 1 is present.
CCP0 Pin Present
When set, indicates that Capture/Compare/PWM pin 0 is present.
ADC Module 0 AIN7 Pin Present
When set, indicates that ADC module 0 input pin 7 is present.
ADC Module 0 AIN6 Pin Present
When set, indicates that ADC module 0 input pin 6 is present.
ADC Module 0 AIN5 Pin Present
When set, indicates that ADC module 0 input pin 5 is present.
