V1 = 0.5 if the ALEW bit = 0, and 1.5 if the ALEW bit = 1.
ALEW bits in the BTRL register.
– For a bus cycle with no ALE, V2 = 1 if CR1/0 = 00, 2 if CR1/0 = 01, 3 if CR1/0 = 10, and 4 if CR1/0 = 11. Note that during burst
– For a bus cycle with an ALE, V2 = the total bus cycle duration (2 if CRA1/0 = 00, 3 if CRA1/0 = 01, 4 if CRA1/0 = 10,
This variable represents the programmed width of the ALE pulse as determined by the ALEW bit in the BTRL register.
This variable represents the programmed width of the PSEN pulse as determined by the CR1 and CR0 bits or the CRA1, CRA0, and
mode code fetches, PSEN does not exhibit transitions at the boundaries of bus cycles. V2 still applies for the purpose of
determining peripheral timing requirements.

Example: If CRA1/0 = 10 and ALEW = 1, the V2 = 4 – (1.5 + 0.5) = 2.
