For More Information On This Product,
TIM overflow flag (TOF) — The TOF bit is set when the TIM
counter value rolls over to $0000 after matching the value in the
TIM counter modulo registers. The TIM overflow interrupt enable
bit, TOIE, enables TIM overflow CPU interrupt requests. TOF and
TOIE are in the TIM status and control register.
TIM channel flags (CH3F–CH0F) — The CHxF bit is set when an
input capture or output compare occurs on channel x. The channel
x interrupt enable bit, CHxIE, enables channel x TIM CPU
interrupt requests. CHxF and CHxIE are in the TIM channel x
status and control register.
SPI receiver full bit (SPRF) — The SPRF bit is set every time a
byte transfers from the shift register to the receive data register.
The SPI receiver interrupt enable bit, SPRIE, enables SPRF CPU
interrupt requests. SPRF is in the SPI status and control register
and SPRIE is in the SPI control register.
SPI transmitter empty (SPTE) — The SPTE bit is set every time a
byte transfers from the transmit data register to the shift register.
The SPI transmit interrupt enable bit, SPTIE, enables SPTE CPU
interrupt requests. SPTE is in the SPI status and control register
and SPTIE is in the SPI control register.
Mode fault bit (MODF) — The MODF bit is set in a slave SPI if the
SS pin goes high during a transmission with the mode fault enable
bit (MODFEN) set. In a master SPI, the MODF bit is set if the SS
pin goes low at any time with the MODFEN bit set. The error
interrupt enable bit, ERRIE, enables MODF CPU interrupt
requests. MODF, MODFEN, and ERRIE are in the SPI status and
control register.
Overflow bit (OVRF) — The OVRF bit is set if software does not
read the byte in the receive data register before the next full byte
enters the shift register. The error interrupt enable bit, ERRIE,
enables OVRF CPU interrupt requests. OVRF and ERRIE are in
the SPI status and control register.
