TS-7300 MANUAL

 

HARDWARE COMPONENTS 

3.5  Real-Time Clock

The  

TS-7300

  optionally   supports   a   Non-volatile   Battery-backed   real-time   clock   (RTC) 

which is soldered onto the board. This option uses an ST Micro M48T86PC1 module for 
the real-time clock function. This module contains the lithium battery, 32.768 kHz crystal, 
and   a   RTC   chip   with   114   bytes   of   battery-backed   CMOS   RAM.   It   will   maintain   clock 
operation for a minimum of 10 years in the absence of power.

The 114 bytes of non-volatile RAM, physically located in the RTC chip, are available to the 
user. Contact Technologic Systems for driver support. 

The   RTC   is   accessed   using   two   registers.   The   write-only   index   register   is   located   at 
physical address location 

0x1080_0000 

and the RTC data register is location at physical 

address   location  

0x1170_0000

.   These   are   byte-wide   registers   with   the   Index   Register 

property of write only. The Data Register has a read/write property. Valid Index Register 
values   are   between   0   and   127,   decimal.   The   first   14   index   locations   are   used   for 
accessing the RTC Time and Date registers. The next 114 locations are non-volatile RAM 
locations. 

This option is NOT compatible with the TS-5620, a peripheral board that also uses an ST 
Micro RTC  module for real-time clock functionality.  While the two options are  mutually 
exclusive, it is possible to use the TS-5620 peripheral board on a 

TS-7300 

that does not 

have   the   on-board   RTC   option   installed.   Any   source   code   that   utilizes   the   RTC   is 
compatible   with   both   optional   installations.  The   TS-Kernel   shipped   with   the   boards 
includes support for the TS-5620 peripheral board.

3.6  Watchdog Timer

The  

TS-7300

  incorporates   a   Watchdog   Timer   (WDT)   unit.   The   WDT   can   be   used   to 

prevent a system “hanging” due to a software failure. The WDT causes a full system reset 
when the WDT times out, allowing a guaranteed recovery time from a software error. To 
prevent   a   WDT   timeout,   the  application   must   periodically   “feed”   the   WDT   by   writing   a 
specific value to a specific memory location. 

Table: Watchdog Control Registers

Address  

Access

WDT Control register  0x2380_0000 

Read/Write

WDT Feed register 

0x23C0_0000 

Write Only

The WDT Control register must be initialized with the timeout period desired. This may be 
as short as 250 mS or may be as long as 8 seconds. After the WDT has been enabled, 
the WDT counter begins. The application software can reset this counter at any time by 
“feeding” the WDT. If the WDT counter reaches the timeout period,  then a full system 
reset occurs.
