When the Timer J is set to the remote controlled operation mode, since the start bit (ST) is being
set or cleared in synchronization with the inputting clock to the TMJ-2, a delay upto a cycle of the
inputting clock at the maximum occurs, namely, after the ST bit has been set to 1 until the remote
controlled data transmission starts. Consequently, when the TLK is updated during the period
after setting the ST bit to 1 until the next cycle of the inputting clock comes, the initial burst width
will be changed as shown in figure 13.4.
Therefore, when making remote controlled data transmission, determine I/O of the TGL bit at the
time of the first burst width control operation without fail. (Or, set the space width to the TLK
after waiting for a cycle of the inputting clock.)
After that, operations can be continued by interrupts.
Similarly, pay attention to the control works when ending remote controlled data transmission.
Example:
1) Set the burst width with the TLK.
2) ST bit ← 1.
3) Execute the procedure 4) if the TGL flag = 1.
4) Set the space width with the TLK under the status where the TGL flag = 1.
5) Make TMJ-2 interrupt.
6) Set the burst width with the TLK.
:
n) After making TMJ-2 interrupt, make setting of the ST ← 0 under the status where the TGL
flag = 0.
