In the inside of LSI, the CLEAR of BUSY bit is performed when
HOLD bit = 0, but, if the period of HOLD bit =0 is extermely
narrow as compared with the period of HOLD bit = 1, there is
some case that the CLEAR of BUSY bit delays so that the
BUSY bit can be cleared by sampling HOLD bit = 0 at approximate
16KHz. It is recommended to allow an idling time of 62
m
s or more.
