This LSI can extend the bus cycle by inserting wait cycles (Tw) when the external address space is
accessed. There are two ways of inserting wait cycles: program wait (Tpw) insertion and pin wait
(Ttw) insertion using the WAIT pin.
(1)
From 0 to 7 wait cycles can be inserted automatically between the T
access space, according to the settings in WTCRA and WTCRB.
(2)
For 3-state access space, when the WAITE bit in BCR1 is set to 1 and the corresponding ICR bit
is set to 1, wait input by means of the WAIT pin is enabled. When the external address space is
accessed in this state, a program wait (Tpw) is first inserted according to the WTCRA and
WTCRB settings. If the WAIT pin is low at the falling edge of Bφ in the last T2 or Tpw cycle,
another Ttw cycle is inserted until the WAIT pin is brought high. The pin wait insertion is
effective when the Tw cycles are inserted to seven cycles or more, or when the number of Tw
cycles to be inserted is changed according to the external devices. The WAITE bit is common to
all areas. For details on ICR, see section 13, I/O Ports.
