General-Purpose Timers
Register 9: GPTM Timer A Interval Load (GPTMTAILR), offset 0x028
When the timer is counting down, this register is used to load the starting count value into the timer.
When the timer is counting up, this register sets the upper bound for When GPTM is configured to
one of the 32-bit modes, GPTMTAILR appears as a 32-bit register (the upper 16-bits correspond
to the contents of the GPTM Timer B Interval Load (GPTMTBILR) register). In 16-bit mode, the
upper 16 bits of this register read as 0s and have no effect on the state of GPTMTBILR.

Reset Description
0xFFFF
GPTM Timer A Interval Load Register High
When configured for 32-bit mode via the GPTMCFG register, the GPTM
Timer B Interval Load (GPTMTBILR) register loads this value on a
write. A read returns the current value of GPTMTBILR.
In 16-bit mode, this field reads as 0 and does not have an effect on the
state of GPTMTBILR.
0xFFFF
GPTM Timer A Interval Load Register Low
For both 16- and 32-bit modes, writing this field loads the counter for
Timer A. A read returns the current value of GPTMTAILR.
