2WTX

R/W

: Places the Timeout Timer in WTX Mode

: Places it in BWT Mode. In WTX Mode, the Timeout Timer

underflow reloads the Timeout Timer instead of stopping it, and the

Receiver is not disabled on underflow.

RSTO

R/W

Reset the Timeout Timer:

This bit reads as 0 always. Writing a 1 to this bit clears the ENTO bit

to 0, and removes any pending interrupt request from the Timeout

Timer.

ENTO

R/W

Writing 1 enables the Timeout Timer to begin counting at the next

triggering event.

Writing 0 has no effect: to clear this bit, write 1 to the RSTO bit in the

Timer Control Register. This bit is cleared by hardware action in order

to stop the timer.

NAME

R/W

DESCRIPTION

7:6

SAMPLING

This field indicates a divisor to apply from the DLL/DLM value in order

to get the final etu rate:

: divide by 31

: divide by 16

: divide by 1

: reserved for future use

The SC_CLK_DIV divisor field is reduced in size to 6 bits

5:0

DIVISOR

R/W

This field gives the divisor to apply to the SEC1110 and SEC1210

system clock in order to generate the SCx_CLK signal to the ICC.
