TIMER4 OR STI TIMER
Timer4 is a general-purpose, 16-bit, count up/count down
timer with a programmable prescaler. Timer4 can be clocked
from the core clock or the low power 32.768 kHz oscillator with
a prescaler of 1, 16, 256, or 32,768.
Timer4 has a capture register (T4CAP) that is triggered by a
selected IRQ source initial assertion. When triggered, the current
timer value is copied to T4CAP, and the timer continues running.
This feature can be used to determine the assertion of an event
with increased accuracy.
Timer4 is also used to drive the serial test interface (STI)
peripheral.
Timer4 interface consists of five MMRs.

Function:
T4LD, T4VAL, and T4CAP are 16-bit registers and hold
16-bit unsigned integers. T4VAL and T4CAP are read only.
T4CLRI is an 8-bit register. Writing any value to this
register clears the interrupt.
T4CON is the configuration MMR described in Table 57.
T4LD
0xFFFF0380
0x00000
Read/write
T4LD 16-bit register holds the 16-bit value
that is loaded into the counter.
T4CLRI
0xFFFF038C
Write only
This 8-bit, write only MMR is written (with
any value) by user code to clear the interrupt.
