Flash Bypass Mode Register Structure
For using Flash controller bypass mode for all package sizes, the signals must be
registered internally. This allows all data access to occur through pin PWM2L and Port A
[6:0]. Three other pins (PWM2H, PWM1L, and PWM1H), selects one of the input data
registers or the data output register as shown in Table 4.
