Description
I2C Module 1 Present
When set, indicates that I2C module 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.
I2C Module 0 Present
When set, indicates that I2C 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.
QEI1 Present
When set, indicates that QEI module 1 is present.
QEI0 Present
When set, indicates that QEI 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.
SSI1 Present
When set, indicates that SSI module 1 is present.
SSI0 Present
When set, indicates that SSI 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.
UART2 Present
When set, indicates that UART module 2 is present.
UART1 Present
When set, indicates that UART module 1 is present.
UART0 Present
When set, indicates that UART module 0 is present.
