| This example project uses the RJ timer to trigger DTC transfers in background. | ||
|
|
||
| The system is driven in stop mode, and uses the 15KHz oscillator (FSUB). | ||
|
|
||
| By default the LED on the RL78 promo board (connected on P7.7) should toggle with a frequency of about 2 sec. | ||
|
|
||
| Port 7 is being written in background with an alternating pattern of 0xFF and 0x0 | ||
|
|
||
| The timer RJ event is processed by the DTC to: | ||
|
|
||
| - configure the next RJ timer match | ||
| - write on the P7 data port | ||
|
|
||
| After this event, the system goes back to stop mode. | ||
|
|
||
| The maximum time interval between measurements is linked to the 15KHz clock and the 16-bit range of the RJ counter, so about 4,3 seconds max. | ||
|
|
||
| The demo has been tested on the RL78G14RPB board (USB-stick form factor promotion board) |
