V850ES/IE2, a wait is required in addition to those 3 clocks. Set 11H (set wait for 2 clocks) to the VSWC register.
The VSWC register is a register that controls the bus access wait for the on-chip peripheral I/O registers.
Access to on-chip peripheral I/O registers of the V850ES CPU core is basically made in 3 clocks; however, in the
This register can be read or written in 8-bit units (address: FFFFF06EH, initial value: 77H).
Caution When using the V850ES/IE2, the VSWC register must be set first.
Remark
System wait control register (VSWC)
Set other registers as needed after setting the VSWC register.
When a register includes status flags that indicate the statuses of the on-chip peripheral functions
(register such as the STATUS1n register) or a register that indicates the count value of a timer is
accessed, a register access retry operation takes place if the timing at which the flag and count value
changes and the timing of the register access overlap. Consequently, access to the on-chip peripheral
I/O register may take a long time.
