Register 19: GPTM Timer B (GPTMTBR), offset 0x04C
This register shows the current value of the Timer B 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.
Note: When an alternate clock source is enabled, a read of this register returns the current count
-1.
When a GPTM is configured to one of the 32-bit modes, the contents of bits 15:0 in this register are
loaded into the upper 16 bits of the GPTMTAR register. Reads from this register return the current
value of Timer B. In a 16-bit mode, bits 15:0 contain the value of the counter and bits 23:16 contain
the value of the prescaler in Input Edge Count, Input Edge Time, and PWM modes, 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 GPTMTBV register. To read the value of the
prescalar in periodic snapshot mode, read the Timer B Prescale Snapshot (GPTMTBPS) register.

GPTM Timer B Register
A read returns the current value of the GPTM Timer B 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.
