Initial value

Read/Write

R/W

Transmit-end interrupt enable

Enables or disables transmit-end

interrupts (TEI)

Multiprocessor interrupt enable

Enables or disables multiprocessor

interrupts

Receive enable

Enables or disables the receiver

Transmit enable

Enables or disables the transmitter

Receive interrupt enable

Enables or disables receive-data-full interrupts (RXI) and

receive-error interrupts (ERI)

Transmit interrupt enable

Enables or disables transmit-data-empty interrupts (TXI)

Clock enable 1/0

These bits select the

SCI clock source

The CPU can always read and write SCR. SCR is initialized to H'00 by a reset and in standby

mode.
