If the time authorize circuit is not used, the system
is reset when a high signal is input for more than 6
msec.
*
If "NOT USE" is set for the combination, the
time authorize selection is required.
The system reset circuit is shown in Figure 3.3.1.
4 Watchdog timer
*** OPTION NO.4 ***
--- WATCHDOG TIMER ---
WATCHDOG TIMER
1. USE
2. NOT USE
PLEASE SELECT NO.(1) ? 1
WATCHDOG TIMER 1. USE SELECTED
Select whether the watchdog timer built-in to detect
CPU runaways will be used or not.
When the watchdog timer is not reset by the
program within 3 to 4 second cycles, the CPU is
initially reset.
5 Input interrupt noise rejector
*** OPTION NO.5 ***
--- I/P INTERRUPUT NOISE REJECTOR ---
K00-K03
1. USE
2. NOT USE
PLEASE SELECT NO.(1) ? 1
K10
1. USE
2. NOT USE
PLEASE SELECT NO.(1) ? 1
K20-K23
1. USE
2. NOT USE
PLEASE SELECT NO.(1) ? 1
K00-K03 1. USE SELECTED
K10 1. USE SELECTED
K20-K23 1. USE SELECTED
Select whether noise rejector will be supplemented
to the input interruptor of K00–K03, K10 and K20–
K23.
When "USE" is selected, the entry signal will pass
the noise rejector, and occurrence of interrupt
errors due to noise or chattering can be avoided.
Note, however, that because the noise rejector
performs entry signal sampling at 4 kHz, "NOT
USE" should be selected when high speed response
is required.
