(5) Automatic transmit/receive interval time
SCKA0
ACSIIF
When using the automatic transmit/receive function, the read/write operations from/to the internal buffer RAM are
performed after transmitting/receiving one byte. Therefore, an interval is inserted before the next transmit/receive
operation.
Since the read/write operations from/to the buffer RAM are performed in parallel with the CPU processing when
using the automatic transmit/receive function by the internal clock, the interval depends on the value which is set
in automatic data transfer interval specification register 0 (ADTI0) and bits 5 (STBE0) and 4 (BUSYE0) of serial
status register 0 (CSIS0).
When ADTI0 is cleared to 00H, an interval time based on the to STBE0 and BUSYE0 settings is inserted. If
ADTI0 = 00H and STBE0 = BUSYE0 = 1, for example, then an interval time of two clocks is inserted, and the
interval time can be further extended by using an external busy signal. If an interval time of two clocks or more is
set by using ADTI0, then the interval time set by ADTI0 is inserted, regardless of the settings of STBE0 and
BUSYE0. When BUSYE0 = 1, the interval time can be further extended by an external busy signal.
Example Interval time when ADTI0 = 00H and busy signal is not generated

<1> When STBE0 = 1, BUSYE0 = 0: Interval time of two serial clocks is generated
<2> When STBE0 = 0, BUSYE0 = 1: Interval time of one serial clock is generated
<3> When STBE0 = 1, BUSYE0 = 1: Interval time of two serial clocks is generated
