transmission/reception, an interval is inserted until the next transmission/reception. As
the buffer RAM write/read is performed at the same time as CPU processing, the interval
is dependent upon the value of automatic data transfer interval specification register 0
(ADTI0) and the set values of bits 5 and 4 (STBE0, BUSYE0) of serial status register 0
(CSIS0) (see (5) Automatic transmit/receive interval time).
