2.3.1.3
After receiving this command, the chip will load in a
14-bit data word when 16 cycles are applied. However,
the data memory is only 8 bits wide and thus, only the
first 8 bits of data after the Start bit will be programmed
into the data memory. It is still necessary to cycle the
clock the full 16 cycles in order to allow the internal
circuitry to reset properly. The data memory contains
128 bytes. Only the lower 8 bits of the PC are decoded
by the data memory and therefore, if the PC is greater
than 0x7F, it will wrap around and address a location
within the physically implemented memory.

2.3.1.4
After receiving this command, the chip will transmit
data bits out of the program memory (user or
configuration) currently accessed, starting with the
second rising edge of the clock input. The data pin will
go into Output mode on the second rising clock edge
and revert to Input mode (high-impedance) after the
16th rising edge.
