Register 9: GPTM TimerA Interval Load (GPTMTAILR), offset 0x028
This register is used to load the starting count value into the timer. 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 TimerB 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.

Preliminary
Description
GPTM TimerA Interval Load Register High
When configured for 32-bit mode via the GPTMCFG register,
the GPTM TimerB 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.
GPTM TimerA Interval Load Register Low
For both 16- and 32-bit modes, writing this field loads the
counter for TimerA. A read returns the current value of
GPTMTAILR.
