2.8 Arithmetic and Logic Unit (ALU): 4 Bits
The arithmetic and logic unit (ALU), which is an arithmetic circuit consisting of 4 bits, executes simple
manipulations with priority given to logical operations.
2.9 Flags
2.9.1 Status flag (F)
Pin and timer statuses can be checked by executing the STTS instruction to check the status flag.
The status flag is set (to 1) in the following cases.
If the condition specified with the operand is met when the STTS instruction has been executed
When standby mode is canceled.
When the cancelation condition is met at the point of executing the HALT instruction. (In this case, the system
is not placed in standby mode.)
Conversely, the status flag is cleared (to 0) in the following cases:
If the condition specified with the operand is not met when the STTS instruction has been executed.
When the status flag has been set (to 1), the HALT instruction executed, but the cancelation condition is not
met at the point of executing the HALT instruction. (In this case, the system is not placed in standby mode.)
