Notes: 1. After reset, the value output is 0 until the first compare match occurs.
10.2.11 Timer Status Register (TSR)
The timer status register (TSR) is an eight-bit read/write register containing flags that indicate
timer counter (TCNT) overflow/underflow and general register (GRA/GRB) compare match or
input capture. These flags are interrupt sources. If the interrupt is enabled by the corresponding bit
in the timer interrupt enable register (TIER), an interrupt request is sent to the CPU. TSR is
initialized to H'F8 or H'78 by a reset and in standby mode. Each ITU channel has one TSR.
