Description

Shadow Tx Empty Trigger Register

Fields

STET

This is a shadow field for the UART_FCR[TET] field. It is used to remove the burden of having to store the previously written value to the UART_FCR[TET] in memory and having to mask this value so that only the UART_FCR[TET] bit gets updated. STET is used to select the empty threshold level at which the THRE interrupts will be generated when the mode is active.

0 (Val_0x0): FIFO empty

1 (Val_0x1): 2 characters in FIFO

2 (Val_0x2): FIFO 1/4 full

3 (Val_0x3): FIFO 1/2 full
