5. EXAMPLE TIMINGS FOR COMMUNICATION
communication. The following seven examples are given:
(1) Master transmission timing example 1
(2) Master transmission timing example 2
(3) Slave data transmission timing example
(4) Master reception timing example
(5) Slave reception timing example 1
(6) Slave reception timing example 2
(7) Broadcast reception timing example
This chapter provides examples of the timings at which the contents of internal registers change during
Timing at which a return code is generated upon the start of master transmission and at the normal termination
of transmission
Timing at which a return code is generated upon the start of master transmission, transmission data empty, and
the suspension of transmission
Timing at which a return code is generated upon the start of slave data transmission and the normal termination
of transmission
Timing at which a return code is generated upon the start of master reception and the normal termination of
reception
Timing at which a return code is generated upon the start of slave reception and the normal termination of
reception
Timing at which a return code is generated upon the start of slave reception, reception buffer full, and the normal
termination of reception
Timing at which a return code is generated upon the occurrence of an error during broadcast reception
