ACC, R ← HCF4~7
The contents of HCF bit 4 to bit 7 (HCF4 to HCF7) are loaded to the data
memory location addressed by R6 to R0 and the ACC. The ACC contents
and the meaning of the bits after execution of this instruction are as follows:
Bit 0
Bit 1
Bit 2
HCF4: "1" when the HOLD mode is released by the falling edge signal at the
INT pin.
HCF5: "1" when the HOLD mode is released by underflow from Timer 1.
HCF6: "1" when the HOLD mode is released by the serial port receiving completely
Bit 3 HCF7: "1" when the HOLD mode is released by the serial port transmitting
completely.
Flag Affected:
MOVA R, HCFL

Machine Code:
01001001
0 R6 R5 R4 R3 R2 R1 R0
Machine Cycle:
1
Operation:
ACC, R ← HCF0~3
Description:
The contents of HCF bit 0 to bit 3 (HCF0 to HCF3) are loaded to the data
memory location addressed by R6 to R0 and the ACC. The ACC contents
and the meaning of the bits after execution of this instruction are as follows:
Bit 0
Bit 1
Bit 2
Bit 3
HCF0: "1" when the HOLD mode is released by
overflow from the Divider 0.
HCF1: "1" when the HOLD mode is released by
underflow from Timer 0.
HCF2: "1" when the HOLD mode is released by
a signal change on port RC.
