D6: NG bit
The main microcontroller verifies the D6 bit using the check sum of data sent from the tuner
microcontroller. If D6 is NG, the main microcontroller sets the D6 bit to 1 (NG) and resends it to the tuner
microcontroller within 10 ms. After receiving D6 bit = 1, the tuner microcontroller invalidates D6 = 1 which
was received before the resent D6 = 1. Thus, the resent data are updated 10 ms later.

D5: POWER
Used to hold the internal data with the tuner in standby state (crystal oscillator in low-current dissipation
mode). Linked to pin 24, I/O port (at power on: Low output, at standby: OPEN output).
