Chapter 1 Overview
Figure 1.4.1 shows a configuration of the flag register (FLG). The function of each flag is detailed below.

(1) Bit 0: Carry Flag (C flag)
(2) Bit 1: Debug Flag (D flag)
(3) Bit 2: Zero Flag (Z flag)
(4) Bit 3: Sign Flag (S flag)
(5) Bit 4: Register Bank Select Flag (B flag)
(6) Bit 5: Overflow Flag (O flag)
(7) Bit 6: Interrupt Enable Flag (I flag)
(8) Bit 7: Stack Pointer Select Flag (U flag)

This flag holds a carry, borrow, or shifted-out bit that has occurred in the arithmetic/logic unit.
This flag enables a single-step interrupt.
When this flag is set (= 1), a single-step interrupt is generated after an instruction is executed. When
an interrupt is acknowledged, this flag is cleared to 0.
This flag is set when an arithmetic operation resulted in 0; otherwise, this flag is 0.
This flag is set when an arithmetic operation resulted in a negative value; otherwise, this flag is 0.
This flag selects a register bank. If this flag is 0, register bank 0 is selected; when the flag is 1,
register bank 1 is selected.
This flag is set when an arithmetic operation resulted in overflow.
This flag enables a maskable interrupt.
When this flag is 0, the interrupt is disabled; when the flag is 1, the interrupt is enabled. When the
interrupt is acknowledged, this flag is cleared to 0.
When this flag is 0, the interrupt stack pointer (ISP) is selected; when the flag is 1, the user stack
pointer (USP) is selected.
This flag is cleared to 0 when a hardware interrupt is acknowledged or the INT instruction of software
interrupt numbers 0 to 31 is executed.
