Preliminary Specifications REV.B
Specifications in this manual are tentative and subject to change
Usage Precautions
Stop Mode and Wait Mode
When returning from stop mode by hardware reset, RESET pin must be set to “L” level until main
clock oscillation is stabilized.
Interrupts
Reading address 0000016
When maskable interrupt is occurred, CPU read the interrupt information (the interrupt number and inter-
rupt request level) in the interrupt sequence.
The interrupt request bit of the certain interrupt written in address 0000016 is then 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.
Setting the stack pointer
The value of the stack pointer immediately after reset is initialized to 000016. Accepting an interrupt before
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 point at the beginning of a program. Concerning the first
instruction immediately after reset, generating any interrupts including the NMI interrupt is prohibited.
The NMI interrupt
As for the NMI interrupt pin, an interrupt cannot be prohibited. Connect it to the VCC pin if unused.
Do not get either into stop mode or into wait mode with the NMI pin set to “L”.
Built-in PROM version
All built-in PROM versions
High voltage is required to program to the built-in PROM. Be careful not to apply excessive voltage. Be es-
pecially careful during power-on.
One Time PROM version
One Time PROM versions shipped in blank, of which built-in PROMs are programmed by users, are also pro-
vided. For these microcomputers, a programming test and screening are not performed in the assembly pro-
cess and the following processes. To improve their reliability after programming, we recommend to program
and test as flow shown in Figure 115 before use.
