SAF-TE Source Code
In addition to these interrupt sources, the SAF-TE firmware uses the
internal watchdog timer (Program Tag WDT_CON, Register 0xFE00) to
generate a soft reset (if the code load flag directs a reboot).
3.4.3.1 Interrupt Service Routines (ISR)
The interrupt service routines are executed when the timer 0 counter rolls
over from 0xFFFF to 0.
The user data stored in
config.timer_init_hi
and
config.timer_init_low
initialize the 16-bit timer and the timer is started.
Timer 0 ISR –
Used to implement a delay on an operation to load code
to the serial EEPROM through the TWS bus. The subroutine
tws_memory_write
checks the value of the global variable
tim0_cnt
after each burst of data is transferred through the bus to the EEPROM.
A delay routine requires three interrupts to Timer 0; that is, this timer
must roll over three times before the next burst of data is sent over the
TWS bus. For further information, see
Section 3.4.2.2, “TWS Data
Transfers,” page 3-30
.
Function Name:
ir_timer0()
Return Value: None.
Timer 1 ISR –
Void Function. Timer 1 is initialized to be a 16-bit timer
but is never utilized.
Function Name:
ir_timer1()
Return Value: None.
Timer 2 ISR –
Void Function. Timer 2 is initialized to be a 16-bit timer
and started at the beginning of the main program. Timer 2 is used to
clock (transmit and receive) the serial bus. It is initialized for a 40 MHz
clock rate with autoreload capability. The output of the serial bus is used
for debugging operations.
Function Name:
ir_timer2()
Return Value: None.
Serial Port ISR –
Void Function.
Function Name:
ir_serial()
Return Value: None.
