6.2.2 Auto-CTS

Setting EFR[7] to ‘1’ enables Auto-RTS. If enabled, data in TX FIFO are determined to be

transmitted or suspended by the value of CTS#. If ‘0’, it means external UART can

receive new data and data in TX FIFO are transmitted through TXD pin. If ‘1’, it means

external UART can not accept more data and data in TX FIFO are not transmitted. But

data being transmitted by then complete transmission. These procedures are performed

irrespective of FIFO modes. While Auto-CTS is enabled, you can verify the input value of

CTS# by FSR[1]. If ‘0’, CTS# is ‘0’ and it means external UART can accept new data,

If ’1’, CTS# is ‘1’ and it means external UART can not accept more data and data in TX

FIFO are not being transmitted. If IER[7] is set to ‘1’, interrupt is generated by Auto-CTS

when the input of CTS# is changed from ‘0’ to ‘1’, and it is shown on ISR[5:0]. Interrupts

generated by Auto-CTS are removed if MSR is read.
