10.5.4
BCR4 is a 32-bit readable/writable register that enables asynchronous input for pins corresponding
to individual bits. When asynchronous input is set (ASYNCn = 1), the sampling timing is one
cycle earlier than when synchronous input is set (ASYNCn = 0). With the synchronous input
setting, ensure that setup and hold times are observed.
The timings shown in this section and section 33, Electrical Characteristics, are all for the case
where synchronous input is set (ASYNCn = 0).
