LM3S8962 Microcontroller
Register 17: Device Capabilities 4 (DC4), offset 0x01C
This register provides a list of features available in the system. The Stellaris family uses this register
format to indicate the availability of the following family features in the specific device: Ethernet MAC
and PHY, GPIOs, and CCP I/Os. The format of this register is consistent with the RCGC2, SCGC2,
and DCGC2 clock control registers and the SRCR2 software reset control register.

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.
Ethernet PHY0 Present
When set, indicates that Ethernet PHY module 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.
Ethernet MAC0 Present
When set, indicates that Ethernet MAC module 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.
1588 Capable
When set, indicates that that EMAC0 is 1588-capable.
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.
GPIO Port G Present
When set, indicates that GPIO Port G is present.
GPIO Port F Present
When set, indicates that GPIO Port F is present.
GPIO Port E Present
When set, indicates that GPIO Port E is present.
