Table 138. Port Response 
Bit | Field  | Value  | Description | 
TIMEOUT_VALUE | 000000h  | Timeout value for all ports on the device. This timeout is for sending a packet to  | |
  | 
  | to  | receiving the corresponding response packet. Max value represents 3 to 6  | 
  | 
  | FFFFFFh  | seconds. The timeout duration can be expressed as:  | 
  | 
  | 
  | Timeout = 15 x ((Prescale Value + 1) x DMA Clock Period x Timeout Value)  | 
  | 
  | 
  | where Prescale value is set in PER_SET_CNTL (offset 0020h) and the Timeout  | 
  | 
  | 
  | value is the decimal representation of this register value. For example, given a  | 
  | 
  | 
  | |
  | 
  | 
  | Timeout duration would be:  | 
  | 
  | 
  | Timeout = 15 x ((4 + 1) x 2.5 ns x 16777216) = 3.15 s  |
