[[BYTE 5]]
READ mode (status request)
status, comparator input voltage status are output to the master device.
bit is set to [1]. The condition for reset to [0], voltage supplied to V
is requested in READ mode, and the status is output. (when V
[0] is output.
output [1], low level status is output is [0]. When voltage applied from 0 V to 1.5 V, output is [0].
When from 2.7 V to 6 V, output is [1].

Bit 1 (POR) indicates the power-on reset operation status. When the power supply of V
Bit 2 (FL) indicates the phase comparator lock status. When locked, [1] is output; when unlocked,
Bit 3 (IP7), bit 4 (IP5) and bit 5 (IP4) indicate the input comparator status. High level status is
the output is ON (normal mode); when set to [1], the output is OFF.
is ON; when set to [1], IF output 1 (pin 21) is ON.
to [1], P0 is ON. (P0) output port can be driven at less than 40 mA.

Byte 5 can be used to set control the output port.
Bit 1 (P7), bit 3 (P5) and bit 4 (P4) are used to control output port P7, P5 and P4.
Bit 2 (P6) is used to control change IF output port. When bit 2 is set to [0], IF output 1 (pin 19)
Bit 8 (P0) is used to control band output port (P0). When bit 8 is set to [0], P0 is OFF; when set
