TEA_OUT[1

TEA Period
This value is multiplied by 2^15 to determine the number of ISF clock
cycles a request waits for an acknowledge before a transaction error
acknowledge (TEA) occurs.
For example, assume the ISF clock is operating at maximum frequency of
156.25 MHz, and TEA_OUT is at its default value of 0x0200. The TEA
timeout period is: (0x0200)
*
2^15 * 6.4 ns = 107.4 ms.
A value of 0x0000 disables the TEA timer.
