G Channel Program Counter Value (G channel PC)
Address 0AH
Reset value 00H
PC registers are synchronized to 32 kHz clock. Delay between consecutive I
μs (typ.). PC register can be read or written only when EXEC mode is 'hold'.
B Channel Program Counter Value (B channel PC)
Address 0BH
Reset value 00H
PC registers are synchronized to 32 kHz clock. Delay between consecutive I
μs (typ.). PC register can be read or written only when EXEC mode is 'hold'.
STATUS/INTERRUPT Register
Address 0CH
Reset value 00H
Note: Register INT bits will be cleared when read operation to Status/Interrupt register occurs. INT output pin (active low) will go
high after read operation.
