Disabling peripherals on PIC24FJ256GB110 [resource]

Posted: Tue Feb 23, 2010 8:29 am

Hi All

Because of my power critical application, I have to disable everything that isn't necessary. Defining all of the stop in idle mode bits and module enable bits took some time, so I've posted them here if it helps anybody else out.

Code:

/******************* STOP IN IDLE MODE BITS (SIDL), MODULE ENABLE BITS ****************************/

// timers
#word T1CON = 0x0104 // timer 1
#bit T1SIDL = T1CON.13
#word T2CON = 0x0110 // timer 2
#bit T2SIDL = T2CON.13
#word T3CON = 0x0112 // timer 3
#bit T3SIDL = T3CON.13
#word T4CON = 0x011E // timer 4
#bit T4SIDL = T4CON.13
#word T5CON = 0x0120 // timer 5
#bit T5SIDL = T5CON.13

// input capture
#word IC1CON1 = 0x140 // input capture 1
#bit IC1SIDL = IC1CON1.13
#word IC2CON1 = 0x148 // input capture 2
#bit IC2SIDL = IC2CON1.13

#bit IC4SIDL = IC4CON1.13
#word IC5CON1 = 0x160 // input capture 5
#bit IC5SIDL = IC5CON1.13
#word IC6CON1 = 0x168 // input capture 6
