For More Information On This Product,
SCI transmitter empty bit (SCTE) — SCTE is set when the SCI
data register transfers a character to the transmit shift register.
The SCI transmit interrupt enable bit, SCTIE, enables transmitter
CPU interrupt requests. SCTE is in SCI status register 1. SCTIE is
in SCI control register 2.
Transmission complete bit (TC) — TC is set when the transmit
shift register and the SCI data register are empty and no break or
idle character has been generated. The transmission complete
interrupt enable bit, TCIE, enables transmitter CPU interrupt
requests. TC is in SCI status register 1. TCIE is in SCI control
register 2.
SCI receiver full bit (SCRF) — SCRF is set when the receive shift
register transfers a character to the SCI data register. The SCI
receive interrupt enable bit, SCRIE, enables receiver CPU
interrupts. SCRF is in SCI status register 1. SCRIE is in SCI
control register 2.
Idle input bit (IDLE) — IDLE is set when 10 or 11 consecutive logic
1s shift in from the RxD pin. The idle line interrupt enable bit, ILIE,
enables IDLE CPU interrupt requests. IDLE is in SCI status
register 1. ILIE is in SCI control register 2.
Receiver overrun bit (OR) — OR is set when the receive shift
register shifts in a new character before the previous character
was read from the SCI data register. The overrun interrupt enable
bit, ORIE, enables OR to generate SCI error CPU interrupt
requests. OR is in SCI status register 1. ORIE is in SCI control
register 3.
Noise flag (NF) — NF is set when the SCI detects noise on
incoming data or break characters, including start, data, and stop
bits. The noise error interrupt enable bit, NEIE, enables NF to
generate SCI error CPU interrupt requests. NF is in SCI status
register 1. NEIE is in SCI control register 3.
