30.3.12 Wait Time Register (SCWAIT)
SCWAIT is a 16-bit readable/writable register. If the interval between the start of two successive
characters exceeds the set value (in etu units), a wait time error is generated.

Description
Wait Time Register
• T=0
In this mode, the operation wait time can be set in this
register. If the interval between the start of characters
to be received and transmitted or received characters
immediately before exceeds the (60 × the value set in
this register) etu, the WAIT_ER flag is set to 1.
However, if SCWAIT is set to H'0000, the WAIT_ER
flag is set after 60 etus.
• T=1
In this mode, the character wait time can be set in this
register. If the interval between the start of two
successive received characters exceeds the (the
value set in this register) etu, the WAIT_ER flag is set
to 1. However, if SCWAIT is set to H'0000, the
WAIT_ER flag is set after 1 etu.
