CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
Consequently, when the input terminal is in the active status (low status), do not rewrite the mask
register (clearing, then setting the mask register), so that a factor flag will only set at the falling edge
in this case. When clearing, then setting the mask register, set the mask register, when the input
terminal is not in the active status (high status).
When an interrupt is triggered at the rising edge of the input terminal, a factor flag will be set at the
timing of shown in Figure 4.4.5.1. In this case, when the mask registers cleared, then set, you should
set the mask register, when the input terminal is in the low status.
In addition, when the mask register = "1" and the content of the input comparison register is rewritten
in the input terminal active status, an input interrupt factor flag may be set. Thus, you should rewrite
the content of the input comparison register in the mask register = "0" status.
(4) Read out the interrupt factor flag (IK) only in the DI status (interrupt flag = "0"). Read-out during EI
status (interrupt flag = "1") will cause malfunction.
(5) Write the interrupt mask register (EIK) only in the DI status (interrupt flag = "0"). Writing during EI
status (interrupt flag = "1") will cause malfunction.
