Register 17: GPTM Timer A (GPTMTAR), offset 0x048
This register shows the current value of the Timer A counter in all cases except for Input Edge Count
and Time modes. In the Input Edge Count mode, this register contains the number of edges that
have occurred. In the Input Edge Time mode, this register contains the time at which the last edge
event took place. Also in Input Edge-Count mode, bits 23:16 contain the upper 8 bits of the count.
When a GPTM is configured to one of the 32-bit modes, GPTMTAR appears as a 32-bit register
(the upper 16-bits correspond to the contents of the GPTM Timer B (GPTMTBR) register). In
the16-bit Input Edge Count, Input Edge Time, and PWM modes, bits 15:0 contain the value of the
counter and bits 23:16 contain the value of the prescaler, which is the upper 8 bits of the count. Bits
31:24 always read as 0. To read the value of the prescaler in 16-bit One-Shot and Periodic modes,
read bits [23:16] in the GPTMTAV register.

GPTM Timer A Register
A read returns the current value of the GPTM Timer A Count Register,
in all cases except for Input Edge Count and Time modes. In the Input
Edge Count mode, this register contains the number of edges that have
occurred. In the Input Edge Time mode, this register contains the time
at which the last edge event took place.
