1. MASK0
2. MASK1
This command is sent by sending binary 000x xxxx data. This can be used to read IC status in the SPI return word. Message
This is the mask for interrupts. A bit set to “1” enables the corresponding interrupt. Because of the number of MASK bits, this
Both are accessed with 0010 xxxx and 0011 xxxx patterns respectively.
CLINT0 and CLINT1 have the same format as MASK0 and MASK1 respectively, but the action is to clear the interrupt latch
NULL Commands are described in detail in the STATUS REGISTERS section of this document.
