inittimer12

InitTimer12

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
prescaler	The value of the prescaler for this specific timer. See the tables below for permitted values.
postscaler	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	PS12_1	0
1:4	PS12_4	1
1:16	PS12_16	2
1:64	PS12_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.

Postcaler Value	Use Numeric Constant
1:1 Postscaler	0
1:2 Postscaler	1
1:3 Postscaler	2
1:4 Postscaler	3
1:5 Postscaler	4
1:6 Postscaler	5
1:7 Postscaler	6
1:8 Postscaler	7
1:9 Postscaler	8
1:10 Postscaler	9
1:11 Postscaler	10
1:12 Postscaler	11
1:13 Postscaler	12
1:14 Postscaler	13
1:15 Postscaler	14
1:16 Postscaler	15
