;Bit equate table
RI_0 equ 98h ;Serial Port 0 Receiver Interrupt Flag
TI_0 equ 99h ;Serial Port 0 Transmitter Interrupt Flag
EX1 equ 0AAh ;External Interrupt 1 Enable bit
F0 equ 0D5h ;General purpose flag.
;Constant equate table
DATA_TABLE equ 0000h ;Put data log table at start of SRAM
cseg at 0 ;Reset vector.
ljmp START
cseg at 13h ;External Interrupt 1 vector.
ljmp EXT_INT1
cseg at 23h ;Serial Interrupt 0 vector.
ljmp SER_INT0
cseg at 6Bh ;Real time clock Interrupt vector.
ljmp RTC_INT
;
cseg at 100H ;Beginning of code segment.
START:
MOV SP, #80h ;Set up stack pointer.
MOV P1, #0FFh ;Set port 1 as inputs.
MOV P3, #0Bh ;Set RXD0, TXD0 & INT1 as inputs.
MOV PMR, #01h ;Select on–chip SRAM.
MOV RTAM, #00h ;Set minute, second, and subsecond alarms.
MOV RTAS, #00h ; Alarm will wake device every hour on the hour
MOV RTASS, #00h ; to initiate temperature gathering.
MOV TA, #0AAh ;Timed access write to enable minute, second,
MOV TA, #55h ; and subsecond compares.
ORL RTCC, #0C1h
MOV SCON0, #050h ;Set serial port 0 for Mode 3
MOV TH1, #0E6h ;Timer 1 reload value for 2400 baud at 24 MHz.
MOV TMOD, #20h ;Set timer 1 to 8–bit auto reload and start it.
MOV TCON, #40h
MOV IP, #10h ;Serial port 0 and RTC high priority interrupts
MOV EIP, #20h ; so they can interrupt Ext. interrupt 1 routine.
MOV EIE, #20h ;Enable Serial port 0, Ext. Int. 1. and
MOV IE, #94h ; RTC interrupts.
;***************************************************************************
;This is the main program loop. It does nothing but wait for interrupts, and
; when they are complete, switches back to the ring oscillator and puts the
; part back into Stop mode.
