;start program after interrupt table
;initialization stuff
;variable space used in hex to asc routine
;stores the current number of seconds
;stores the current number of minutes
;stores the current number of hours
;The following section is normally part of
;INCLUDE 'INITSYS.ASM', but we want to
;leave the COP on.
;point EK to bank F for register access
;point XK to bank 0
;point YK to bank 0
;point ZK to bank 0
;initialize the SIM MCR
;this is redundant; it happens at reset
;set system clock to 16.78 Mhz
;enable the watchdog (COP)
;and set time-out period to 8 seconds
;set the periodic interrupt at request level 6
;& assign vector #56 (address $00070) to it
;initialize PITR to interrupt every 1 sec
;initialize Chip Sel Base Reg for Autovector
;on an IACK cycle: A24-A11=$FFF8, blK_sz = 8K
;initialize Chip Sel Option Reg for
;asynchronous, any Interrupt Priority Level
;set port F pins to be IRQ pins
;this is redundant: it happens at reset
;set zk nibble to bank 1 for variable access
;index those variables from $10000
;clear sccnt register
;clear mncnt register
;clear hrcnt register
;clear “save” variable space
;find out who caused the last reset
;turn on internal SRAM at $10000
;set stack in bank 1 (SK=1, SP=03FE)
;set SCI baud rate at 9600 baud
;enable SCI transmitter and receiver
