including the first read byte. This ensures that the first data is captured from the first
address set up by PROG_COMMANDS, and reading the last location in the page makes
the program counter increment into the next page.
Figure 134. Flash Data Byte Register
The state machine controlling the Flash Data Byte Register is clocked by TCK. During
normal operation in which eight bits are shifted for each Flash byte, the clock cycles
needed to navigate through the TAP controller automatically feeds the state machine for
the Flash Data Byte Register with sufficient number of clock pulses to complete its oper-
ation transparently for the user. However, if too few bits are shifted between each
Update-DR state during page load, the TAP controller should stay in the Run-Test/Idle
state for some TCK cycles to ensure that there are at least 11 TCK cycles between each
Update-DR state.
All references below of type “1a”, “1b”, and so on, refer to Table 131.
