Description
Timer 1 Reset Control
When this bit is set, General-Purpose Timer module 1 is reset. All internal
data is lost and the registers are returned to their reset states. This bit
must be manually cleared after being set.
Timer 0 Reset Control
When this bit is set, General-Purpose Timer module 0 is reset. All internal
data is lost and the registers are returned to their reset states. This bit
must be manually cleared after being set.
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.
I2C1 Reset Control
When this bit is set, I2C module 1 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
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.
I2C0 Reset Control
When this bit is set, I2C module 0 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
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 Reset Control
When this bit is set, SSI module 1 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
SSI0 Reset Control
When this bit is set, SSI module 0 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
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

UART2 Reset Control
When this bit is set, UART module 2 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
UART1 Reset Control
When this bit is set, UART module 1 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
