into theT1 Low Order Register.
8 bits from T1 low order latches transferred to MPU. Unlike reading the T1 Low
Order Register, this does not cause reset of T1 interrupt flag IFR6.
8 bits loaded into T1 high order latches. Unlike writing to the T1 Low Order
Register, no latch to counter transfers takes place. T1 interrupt flag IFR6 is
reset.
8 bits from T1 high order counter transferred to MPU.
