Function
If the Condition Code evaluates True, load the BC Time Tag
Count Register 0x0043 with the parameter-specified Time
Value. This represents bits 15-0 when the BC operates
with 32-bit time tag. Otherwise (Condition Code Evaluates
False), continue execution at the next op code in the BC
Instruction List.
Read LTH regarding LTT-LTH sequences.
If the Condition Code evaluates True, load the BC Time Tag
Count High Register 0x0044 with the parameter-specified
Time Value. This represents bits 31-16 when BC operates
with 32-bit time tag.
Otherwise (Condition Code Evaluates False), continue
execution at the next op code in the BC Instruction List.
If LTH immediately follows an LTT instruction, all 32 counter
bits are loaded simultaneously. If LTH is not preceded by
an LTT instruction, time count bits 15-0 in 0x0043 will be
cleared to 0x0000 when bits 31-16 are written to register
0x0044.
This instruction is only allowed when BCTT32 bit 3 is logic
1 in the Time Tag Counter Configuration register 0x0039,
selecting 32-bit time base operation for the BC and RT(s).
If BCTT32 is logic 0, this instruction stops instruction list
execution, and generates an illegal instruction BCTRAP
interrupt, if enabled.
If the Condition Code evaluates True, load the BC Frame
Time Remaining Register 0x0035 with the parameter-
specified Time Value. Otherwise (Condition Code Evaluates
False), continue execution at the next op code in the BC
Instruction List.
If the Condition Code evaluates True, start decrementing
the BC Frame Time Remaining Register 0x0035. Otherwise
(Condition Code Evaluates False), continue execution at the
next op code in the BC Instruction List.
If the Condition Code evaluates True, push the value in the
BC Time Tag Count Register 0x0043 onto the BC General
Purpose Queue. Otherwise (Condition Code Evaluates
False), continue execution at the next op code in the BC
Instruction List.
