InterruptMitsubishi microcomputers<strong>M16C</strong> / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER4.7 Precautions for Interrupts(1) Reading address 0000016• When maskable interrupt is occurred, CPU read the interrupt information (the interrupt number andinterrupt request level) in the interrupt sequence.The interrupt request bit of the certain interrupt written in address 0000016 will then be set to “0”.Reading address 0000016 by software sets enabled highest priority interrupt source request bit to “0”.Though the interrupt is generated, the interrupt routine may not be executed.Do not read address 0000016 by software.(2) Setting the stack pointer• The value of the stack pointer immediately after reset is initialized to 000016. Accepting an interruptbefore setting a value in the stack pointer may become a factor of runaway. Be sure to set a value in_______the stack pointer before accepting an interrupt. When using the NMI interrupt, initialize the stack pointat the beginning of a program. Concerning the first instruction immediately after reset, generating any_______interrupts including the NMI interrupt is prohibited._______(3) The NMI interrupt_______•The NMI interrupt can not be disabled. Be sure to connect NMI pin to Vcc via a pull-up resistor ifunused._______• The NMI pin also serves as P85, which is exclusively input. Reading the contents of the P8 registerallows reading the pin value. Use the reading of this pin only for establishing the pin level at the time_______when the NMI interrupt is input._______• Do not reset the CPU with the input to the NMI pin being in the “L” state._______• Do not attempt to go into stop mode with the input to the NMI pin being in the “L” state. With the input to_______the NMI being in the “L” state, the CM10 is fixed to “0”, so attempting to go into stop mode is turneddown._______• Do not attempt to go into wait mode with the input to the NMI pin being in the “L” state. With the input to_______the NMI pin being in the “L” state, the CPU stops but the oscillation does not stop, so no power is saved.In this instance, the CPU is returned to the normal state by a later interrupt._______• Signals input to the NMI pin require an “L” level of 1 clock or more, from the operation clock of the CPU.(4) External interrupt• Either an “L” level or an “H” level of at least 250 ns width is necessary for the signal input to pins INT0through INT2 regardless of the CPU operation clock.• When the polarity of the INT0 to INT2 pins is changed, the interrupt request bit is sometimes set to “1”.After changing the polarity, set the interrupt request bit to “0”. Figure 4.7.1 shows the procedure for______changing the INT interrupt generate factor._______504
