Preliminary Specification
Specifications in this preliminary version are subject to change.
R32C/152 Group
2. Central Processing Unit (CPU)
2.1.8.5
Register Bank Select Flag (B flag)
This flag selects a register bank. It indicates 0 when the register bank 0 is selected, and 1 when the reg-
ister bank 1 is selected.
2.1.8.6
Overflow Flag (O flag)
This flag becomes 1 if an operation results in an overflow; otherwise, it indicates 0.
2.1.8.7
Interrupt Enable Flag (I flag)
This flag enables a maskable interrupt. It indicates 0 when an interrupt is disabled, and 1 when an inter-
rupt is enabled. Once an interrupt is accepted, the flag is set to 0.
2.1.8.8
Stack Pointer Select Flag (U flag)
This flag indicates 0 when the interrupt stack pointer (ISP) is selected, and 1 when the user stack
pointer (USP) is selected.
It is set to 0 when a hardware interrupt is accepted or the INT instruction whose software interrupt
number is 0 to 127 is executed.
2.1.8.9
Floating-point Underflow Flag (FU flag)
This flag becomes 1 if a floating point operation results in an underflow; otherwise it indicates 0. It also
becomes 1 when the operand has invalid numbers (subnormal numbers).
2.1.8.10
Floating-point Overflow Flag (FO flag)
This flag becomes 1 if a floating point operation results in an overflow; otherwise it indicates 0. It also
becomes 1 when the operand has invalid numbers (subnormal numbers).
2.1.8.11
Processor Interrupt Priority Level (IPL)
The 3-bit processor interrupt priority level (IPL) specifies eight processor interrupt priority levels from 0
to 7. If a requested interrupt's priority level is higher than the processor interrupt priority level (IPL), this
interrupt is enabled.
If the processor interrupt priority level (IPL) is set to 111b (level 7), any interrupt is disabled.
2.1.8.12
Fixed-point Designation Bit (DP bit)
This bit designates a fixed point. It also designates which part of the multiplication result should be
taken. It is used for MULX instruction.
2.1.8.13
Floating-point Rounding Mode (RND)
The 2-bit floating point rounding mode designates a rounding mode for the operation result.
2.1.8.14
Reserved
The fields are written with 0. The read value is undefined.
