Preliminary
Figure 10-2 shows the definitions of the following signal states:
Active state, when a bus or signal is driven, and enters a low impedance state
Tri-stated, when a bus or signal is placed in a high impedance state
Data Valid state, when a signal level has reached VOL or VOH
Data Invalid state, when a signal level is in transition between VOL and VOH

Program time1
1. There is additional overhead which is part of the programming sequence. See the 56F8300 Peripheral User Manual for details.
Program time is per 16-bit word in Flash memory. Two words at a time can be programmed within the Program Flash module,
as it contains two interleaved memories.

Erase time2
2. Specifies page erase time. There are 512 bytes per page in the Data and Boot Flash memories. The Program Flash module
uses two interleaved Flash memories, increasing the effective page size to 1024 bytes.
