Hello,
It seem that enabling irq interrupt can be done in the following two ways:
1. Enabling irq bit in INTCPS_CONTROL register (page 2429 in TRM, register 0x48 in INT section)
2. Enabling irq bit in CPSR_c ARM register.
Are this the same operations ? I mean is doing (1) equals (2) ?
if not - When do we enable interrupt by (1) and when by (2) ? or do we need to do both ?
Thank you,
Ran
