(5) Read Status Register Command
This command reads status information. When the "7016" command code is sent with the 1st byte, the con-
tents of the status register (SRD) specified with the 2nd byte and the contents of status register 1 (SRD1)
specified with the 3rd byte are read.

(6) Clear Status Register Command
This command clears the bits (SR4 - SR5) which are set when the status register operation register operation
ends in error. When the "5016" command code is sent with thefirst byte, the aforementioned bits are cleared.
When the clear status register operation ends, the RTS0 (Busy) signal changes from the "H" to the "L" level.
