0b10: Round towards Minus Infinity (RM) mode.
0b11: Round towards Zero (RZ) mode.
The specified rounding mode is used by almost all floating-point instructions.
 IDC: Input Denormal Cumulative Exception
IDC is a cumulative exception bit for floating-point exception; see also bits [4:0].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
 IXC: Inexact Cumulative Exception
IXC is a cumulative exception bit for floating-point exception; see also bit [7].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
 UFC: Underflow Cumulative Exception
UFC is a cumulative exception bit for floating-point exception; see also bit [7].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
 OFC: Overflow Cumulative Exception
OFC is a cumulative exception bit for floating-point exception; see also bit [7].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
 DZC: Division by Zero Cumulative Exception
DZC is a cumulative exception bit for floating-point exception; see also bit [7].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
 IOC: Invalid Operation Cumulative Exception
IOC is a cumulative exception bit for floating-point exception; see also bit [7].
This bit is set to 1 to indicate that the corresponding exception has occurred since 0 was last written to it.
