EQUATIONS

; -----------------------------------------------------------------------

; Power-on Indicator (Flip-Flop) :

; -----------------------------------------------------------------------

PONFLAG.CLKF = RESETIN ; Power-on-Flag ist 0 at Pon ; otherwise 1

PONFLAG := 1

; -----------------------------------------------------------------------

; Equations for Modes (Reset-States) :

; -----------------------------------------------------------------------

; --------------------> LEDRED is indicating the Monitor-Reset state, if

LEDRED = USERRES * FLASHRES * /MONRES ; Mon-reset button pressed

+ /DTR ; or uart-reset (DTR line low)

+ (/PONFLAG * /DEFAULT) ; or Power-on (Default-Mode=Mon)

+ /LEDGRN * /LEDYEL ; (hold-condition)

; --------------------> LEDGRN is indicating the User-Reset state, if

LEDGRN = /USERRES * FLASHRES * MONRES ; User-Reset button pressed

+ (A20 * /A19 * /CS2) ; or Remote-User-reset request

+ /LEDYEL * /LEDRED ; (hold-condition)

; --------------------> LEDYEL is indicating the Flash-Reset state, if

LEDYEL = USERRES * /FLASHRES * MONRES ; Flash-Reset button pressed

+ (/PONFLAG * DEFAULT) ; or Power-on (Default-Mode=Flash)

+ /LEDGRN * /LEDRED ; (hold-condition)

MODE = LEDGRN ; Mode-Pin (MD0) is 1, if User-Reset state, otherwise 0

PG5 = LEDYEL ; Flash-Ind-Pin is 1, if Flash-Reset state, otherwise 0

UARTRES = /RESETIN * LEDRED ; UART-reset only if Monitor-Reset

; -----------------------------------------------------------------------

; Reset-Request : Toggles the Masterreset-input (MAX811), if

; -----------------------------------------------------------------------

/MASTRES = ((/MONRES + /USERRES + /FLASHRES) * RESETIN) ; Buttons pressed

+ (( LEDGRN * /A19 * A20 ) * RESETIN) ; or Rem-Request

+ ((/DTR ) * RESETIN) ; or DTR low
