Preliminary Technical Data
TIMER1
Timer1 is a 32-bit general purpose timer, count-down or count-
up, with a programmable pre-scalar. The pre-scalar source can
be the Low Power 32.768kHz Oscillator, the core clock, or from
one of two external GPIO. This source can be scaled by a factor
of 1, 16, 256 or 32768. This gives a minimum resolution of
48.83ns when operating at CD zero, the core is operating at
20.48MHz, and with a pre-scalar of 1 ( Ignoring external
GPIO).
The counter can be formatted as a standard 32-bit value or as
Hours:Minutes:Seconds:Hundreths.
Timer1 has a capture register (T1CAP), which can be triggered
by a selected IRQ’s source initial assertion. Once triggered, the
current timer value is copied to T1CAP, and the timer keeps
running. This feature can be used to determine the assertion of
an event with increased accuracy.
- T1LD, T1VAL and T1CAP are 32-bit registers and hold 32-
- T1CLRI is an 8-bit register. Writing any value to this register
- T1CON is the configuration MMR described in below.
Timer1 features a post-scalar. This allows the user to count
between1 and 256 the number of timer1 timeouts. To activate
the post-scalar, the user sets bit 23 and writes the desired
number to count into bits 24-31 of T1CON. Once that number
of timeouts has reached, Timer1 will generate an interrupt if
T1CON[18] is set.
Timer1 interface consists of five MMRS:
bit unsigned integers. T1VAL and T1CAP are read-only.
will clear the timer1 interrupt.
