My project uses a 16F1936 on both a Master and a Slave board. Durring the program the Master sends a code for the Slave to run a subroutine to SLEEP. I am trying to use ASM SLEEP as to NOT designate a time to wake. twenty two hours after the slave enters sleep it recieves a USART comm which should WAKE the slave from SLEEP. Problem is the slave is not going to sleep, or it wakes right away after the command. So, how to trouble shoot SLEEP? I can't monitor the STATUS, PD bit while in sleep, I can only use an indicator LED when going into the SLEEP instruction and toggle it off when exit the sleep instruction, and it is toggling right away.
One observation is that PBP asks for a period whenever I type SLEEP in the ASM module. Can PBP tell the difference between ASM SLEEP and PBP SLEEP or are they both seen as a PBP command? Comments please.
Code:
  ;Slave Board
    PortA.1=1	Indicator LED

RXceiveINT:
    INTbit=1             'Set Cvar to break out of Start loop                                                                                           
    Com_Enable=0       ' Con_enable not needed to RX
    hserin [Bvar] 
@ INT_RETURN    ;goes back to INTerrupt locaion. which is Start loop.

    busy=1
    Select Case Bvar
            Case 0 ;No action taken if Not in Sleep Mode, Return only
@   nop            ;If in Sleep Mode, Wake up, goto Start

            Case 1
                gosub Ran_num

            case 4
                gosub Desolve
            case 5
                gosub FlashFlies
            CASE 6
                gosub  SleepMode	;subroutine to place Slave in Sleep mode
    end select
    busy=0             
    return

;------------------Case6
SleepMode:
    PortA.1=0     ;Indicator LED out on entering SLEEP
ASM
    BTFSS   BAUDCON,RCIDL  ;Check for High, no receive in progress
    GOTO $-1                
    BSF BAUDCON,WUE        ;Wake on Rx from Master

    nop
    nop
ENDASM
    PortA.1=1                   ;Indicator LED ON  at exit SLEEP
    return
    end
The Master does not use the comm line for the next 22 hours.
