ICS0 – Interrupt 0 Cause Set Register
Software uses this register to set an interrupt condition. Assuming the interrupt mask
is set, any bit written with a 1 triggers the corresponding interrupt, see “IMS0 –
Interrupt 0 Mask Set/Read Register” on page 1459 and “ICR0 – Interrupt 0 Cause Read
Register” on page 1454.
