Section 10 16-Bit Integrated Timer Unit (ITU)
10.2.12 Timer Status Register (TSR)
TSR is an 8-bit register. The ITU has five TSRs, one in each channel.
Channel

Each TSR is an 8-bit readable/writable register containing flags that indicate TCNT overflow or
underflow and GRA or GRB compare match or input capture. These flags are interrupt sources
and generate CPU interrupts if enabled by corresponding bits in TIER.
TSR is initialized to H'F8 by a reset and in standby mode.
Bits 7 to 3—Reserved: Read-only bits, always read as 1.
