(4) Burst write cycle
Burst write cycles are used to transfer data from built-in memory to a memory space in four-word
(16-byte) units. They cannot be used to access an I/O space.
The rising edge of the bus clock in the Ta state triggers the output of the address and the activation of
BCYST to signify the beginning of a bus cycle. For access to a space which involves chip select output,
CSn is also output at the same timing.
The bus then enters to the Tb1 state. In this state, the address is output as is and BCYST becomes inactive.
Also, the write data is output at the rising edge of the bus clock. READY is sampled at the rising edge
of the first bus clock after the end of the Tb1 state. If READY is inactive, the bus enters the Tb1 state
(wait) again. Thereafter, each time the Tb1 state ends, READY is sampled. When READY becomes
active, the bus enters the Tb2 state. In the Tb2 state, the address and write data are output on the rising
edge of the bus clock and READY is sampled at the same timing as in the Tb1 state. The same timing
also applies to the subsequent Tb3 to Tb8 states.
