Description (2/2)
[data5]
The number of wait cycles used for second and subsequent accesses during a page read
sequence (CSPRWAIT). Valid between 0 and 7.
[data6]
The number of wait cycles used for second and subsequent accesses during a page write
sequence (CSPWWAIT). Valid between 0 and 7.
[data7]
The number of wait cycles for the first access during a normal or page read sequence (CSRWAIT).
Valid between 0 and 31.
[data8]
The number of wait cycles for the first access during a normal or page write sequence (CSWWAIT).
Valid between 0 and 31.
[data9]
The number of cycles that the CS signal is left asserted after the read strobe is negated (CSROFF).
Valid between 0 and 7.
[data10]
The number of cycles that the CS signal is left asserted after the write strobe is negated
(CSWOFF). Valid between 0 and 7.
[data11]
The number of cycles that the data output is left asserted after the write strobe is negated
(WDOFF). Valid between 0 and 7.
[data12]
The number of cycles before the read strobe is asserted (RDON). Valid between 0 and 7.
[data13]
The number of cycles before the write strobe is asserted (WRON). Valid between 0 and 7.
[data14]
The number of cycles before the write data is output (WDON). Valid between 1 and 7.
[data15]
The number of cycles before the chip select is asserted (CSON). Valid between 0 and 7.
Return value
True if all parameters are valid and exclusive; otherwise false.

Remarks
•
Ensure that function R_BSC_Create is called once before using this function.
•
The endian mode of the CPU is selected by the MDE pin (low = little endian; high = big endian).
•
Port Function Control registers PF0CSE and PF5BUS are modified by this function.
•
The cycle count parameters are not checked for validity. Use the hardware manual to check
these values.
•
Setting single write strobe mode is prohibited in the 8-bit bus space.
•
The available parameter options will be different for different pin packages. Please refer to the
hardware manual for more details.
