MBP
Memory Block Program.
When 1, the connection memory block programming
feature is ready for the programming of Connection Memory high bits, bit 11 to bit 15.
When 0, this feature is disabled.

MS
Memory Select.
When 0, connection memory is selected for read or write operations.
When 1, the data memory is selected for read operations and connection memory is
selected for write operations. (No microprocessor write operation is allowed for the
data memory.)

STA3-0
Stream Address Bits
. The binary value expressed by these bits refers to the input or
output data stream, which corresponds to the subsection of memory made accessible
for subsequent operations. (STA3 = MSB, STA0 = LSB)
