15.3.10 Serial Expansion Mode Register (SEMR_0)
SEMR_0 is an 8-bit register that expands SCI_0 functions; such as setting of the base clock,
selecting of the clock source, and automatic setting of the transfer rate.
Note: Supported only by the H8S/2239 Group only.

Description
SCI_0 Select Enable
This bit enables or disables the SCI_0 select
function when an external clock is input in clocked
synchronous mode. When 1 is set to the
PG1/IRQ7 pin, while the SCI_0 select function is
enabled, the TxD0 output becomes Hi-Z and the
SCK0 input in this LSI is fixed high making the
SCI_0 data transfer terminated. The SSE setting is
valid when the external clock input is selected
(CKE in SCR = 0) in clocked synchronous mode
(C/A in SMR = 1).
0: SCI_0 select is disabled.
1: SCI_0 select is enabled.
When then PG1/IRQ7 pin = 1, the TxD0 output
becomes Hi-Z and the SCK0 clock input is fixed
high.
Reserved
These bits are always read as 0, and cannot be
modified.
Asynchronous Base Clock Select
Selects the 1-bit-interval base clock in
asynchronous mode.
The ABCS setting is valid in asynchronous mode
(C/A in SMR = 0).
0: Operates on a base clock with a frequency of 16
1: Operates on a base clock with a frequency of 8
