The interrupt will remain asserted as long as this bit is set and at least one of
the bits in the interrupt status register is set. Unfortunately, setting this bit to 0
does not disable interrupts due to ram parity-error and cstart out-of-lock. They
need to be disabled separately. Ram parity-error interrupt may be disabled
using bit 5 of “EXTENDED_CHIP_MODE” on page 97. Cstart out-of-lock
interrupt may be disabled using bit 6 of “CONTROL_REGISTER” on page
103.
Global interrupt enabled.
Global interrupt disabled.
SW_RESET

Writing a one to this bit will put the chip in software reset. This means
that the processor interface will remain untouched, and the remaining
blocks in the chip will be reset only some portion of their state (depending
on the discretion of the designer).
Writing a zero to this bit will take the chip out of software reset.
0
Upon pin-reset, this bit comes up as a one. A zero must be explicitly written to
this bit before the chip can function normally.
