Preface
Thank you very much for making use of Toshiba microcomputer LSIs.
Before use this LSI, refer the section, “Points of Note and Restrictions”.
Especially, take care below cautions.
**CAUTION**
How to release the HALT mode
Usually, interrupts can release all halts status. However, the interrupts
=
(
NMI
,
INT0), which can release the HALT mode may not be able to do so if they are
input during the period CPU is shifting to the HALT mode (for about 3 clocks of
f
FPH
) with IDLE1 or STOP mode (IDLE2/RUN are not applicable to this case). (In
this case, an interrupt request is kept on hold internally.)
If another interrupt is generated after it has shifted to HALT mode completely,
halt status can be released without difficultly. The priority of this interrupt is
compare with that of the interrupt kept on hold internally, and the interrupt with
higher priority is handled first followed by the other interrupt.

Outline and Device Characteristics
The TMP93PW46A is OTP type MCU which includes 128-Kbyte One-time PROM. Using the
adapter-socket, you can write and verify the data for the TMP93CW46A by general EPROM
programmer.
The TMP93PW46A has the same pin-assignment as the TMP93CW46A (Mask ROM type).
Writing the program to built-in PROM, the TMP93PW46A operates as the same way as the
TMP93CW46A.
