The Programmable Wait Control Register (PWCON) is an 8-bit read/write register whose two
halves specify the number of programmable wait cycles automatically inserted for accesses to
the SRAM banks (0 and 1).
After a system reset, this register contains 0x77.
Bit Descriptions
PWNn (n=0,1)
This field specifies the number of wait cycles automatically inserted for accesses to bank n. The
range is from 0 (no pausing) to 7.

A "0” indicates a reserved bit. Always write "0” to it.
Writing "1” produces unreliable operation.
