INTERRUPT ENABLE & DISABLE
(ADSP-217x, ADSP-218x, ADSP-21msp58/59 only)
Syntax:
ENA INTS ;
DIS INTS ;
Description: Interrupts are enabled by default at reset. Executing the
DIS INTS instruction causes all interrupts (including the powerdown
interrupt) to be masked, without changing the contents of the IMASK
register.
Executing the ENA INTS instruction allows all unmasked interrupts to be
serviced again.
Note: Disabling interrupts does not affect serial port autobuffering or
ADSP-218x DMA transfers (IDMA or BDMA). These operations will
continue normally whether or not interrupts are enabled.
Status Generated: None affected.
