18.4.5 Timer x Raw Interrupt Status Register

Table 18-9. TIMx_RIS
Bit NumberNameR/WReset ValueDescription
31:1ReservedR/W0Software should not rely on the value of a reserved bit. To provide compatibility with future products, the value of a reserved bit should be preserved across a read-modify-write operation.
0TIMx_RISR/W0Timer x raw interrupt status (RIS)

0: Timer x has not reached zero

1: Timer x has reached zero at least once since this bit was last cleared (by a reset or by writing 1 to this bit).

Writing a 1 to this bit clears the bit and the interrupt, writing a zero has no effect.

Writing this register when the Timer is set to 64-bit mode has no effect. Reading this register when the Timer is set to 64-bit mode returns the reset value.
