Syntax:
InitTimer12 prescaler, postscaler
Command Availability:
Available on Microchip microcontrollers with a Timer 12 module.
Explanation:
Parameters for this timer are detailed in the table below:
| Parameter | Description |
|---|---|
|
|
The value of the prescaler for this specific timer. See the tables below for permitted values. |
|
|
The value of the postscaler for this specific timer. See the tables below for permitted values. |
prescaler can be one of the following settings:
| Prescaler Value | Primary GCB Constant | Constant Equates to value |
|---|---|---|
|
1:1 |
|
0 |
|
1:4 |
|
1 |
|
1:16 |
|
2 |
|
1:64 |
|
3 |
Note that a 1:64 prescale is only avaialable on certain midrange microcontrollers. Please refer to the datasheet to determine if a 1:64 prescale is supported by a spectific microcontroller.
postscaler slows the rate of the interrupt generation (or WDT reset) from a
counter/timer by dividing it down.
On Microchip PIC microcontroller one of the following constants where the Postscaler Rate Select bits are in the range of 1 to 16.
