TIMER1
Timer1 is a general-purpose, 32-bit up/down counter with a
programmable prescaler. The prescaler source can be the low
power 32.768 kHz oscillator, the core clock, or from one of two
external GPIOs. This source can be scaled by a factor of 1, 16,
256, or 32,768. When the core is operating at 20.48 MHz and at
CD = 0 with a prescaler of 1 (ignoring the external GPIOs), a
minimum resolution of 48.83 ns results.
The counter can be formatted as a standard 32-bit value or as
time expressed as hours:minutes:seconds:hundredths.
Timer1 has a capture register (T1CAP) that is triggered by the
initial assertion of a selected IRQ source. When the capture
register is triggered, the current timer value is copied to
T1CAP, and the timer continues to run. This feature can be
used to determine the assertion of an event with increased
accuracy.
The Timer1 interface consists of five MMRS.
T1LD, T1VAL, and T1CAP are 32-bit registers and hold
32-bit unsigned integers. T1VAL and T1CAP are read only.
T1CLRI is an 8-bit register. Writing any value to this
register clears the Timer1 interrupt.
T1CON is a configuration MMR and is described in Table 53.
Timer1 features a postscaler that allows the user to count the
number of Timer1 timeouts between 1 and 256. To activate the
postscaler, the user sets Bit 23 and writes the desired number to
count into Bits[24:31] of T1CON. When this number of
timeouts is reached, Timer1 generates an interrupt if
T1CON[18] is set.
Note that if the part is in a low power mode and Timer1 is
clocked from the GPIO or low power oscillator source, then
Timer1 continues to operate.
Timer1 reloads the value from T1LD when Timer1 overflows.
Timer1 Load Registers
Name:
T1LD
Address:
0xFFFF0320
Default Value:
After a reset, this register contains the upper
half of the assembly lot ID.
Access:
Read/write
Function:
T1LD is a 32-bit register that holds the 32-bit
value that is loaded into the counter.
Timer1 Clear Register
Name:
T1CLRI
Address:
0xFFFF032C
Access:
Write only
Function:
This 8-bit, write only MMR is written (with
any value) by user code to clear the interrupt.
Timer1 Value Register
Name:
T1VAL
Address:
0xFFFF0324
Default Value:
0xFFFFFFFF
Access:
Read only
Function:
T1VAL is a 32-bit register that holds the
current value of Timer1.
