Prom Mode; Input/Output Circuiry - Toshiba TLCS-870/C Series Manual

16.1.1.3 Input/Output Circuiry

1. Control pins
The control pins of the TMP86PM29BUG are the same as those of the
TMP86Cx20,CH21,Cx29B except that the TEST pin does not have a built-in pull-down resis-
tor.
2. I/O ports
The I/O circuitries of the TMP86PM29BUG I/O ports are the same as those of the
TMP86Cx20,CH21,Cx29B.

16.1.2 PROM mode

The PROM mode is set by setting the
ure 16-2. The programming and verification for the internal PROM is acheived by using a general-purpose
PROM programmer with the adaptor socket.

Note 1: The high-speed program mode can be used. The setting is different according to the type of PROM pro-
grammer to use, refer to each description of PROM programmer.
TMP86PM29BUG does not support the electric signature mode, apply the ROM type of PROM programmer
to TC571000D/AD.
Note 2: No pin is applied to A16 pin of TC571000D/AD(Open) in PROM mode.
Always set the adapter socket switch to the "N" side when using TOSHIBA's adaptor socket.
