24.3.12 Service Request Registers
The bits in the Service Request State Registers are service request status flags that are
set by hardware (type "h") when the related event occurs. Each service request status
flag can be read twice (in SRSCx register and in SRSSx register, x = 0-3) and cleared or
set by software when writing to the specific request bit in SRSCx or SRSSx.
The service request status flags can be cleared by software when writing a 1 to the
corresponding bit location in the SRSCx registers. Writing a 0 has no effect.
The service request status flags can be set by software when writing a 1 to the
corresponding bit location in the SRSSx registers. Writing a 0 has no effect.
