10. MAIN SYSTEM CONTROLLER IC6005
The main system controller IC6005 starts up when 1.10[V] and 3.0[V] are supplied and the reset releasing signal (“H”) is supplied. And also PLD IC8001 starts up
when 1.8[V] and 3.0[V] is supplied and the reset releasing signal (“H”) is supplied.
When Main System Controller IC6005 starts up, the timing generator circuit inside IC6005 starts the operation and X6001 starts oscillating. Then, the clock, 256fs
(11289.6[kHz]) is supplied to PLD IC8001 and IC8001 starts operation. And also, when IC6005 starts up, IC6005 downloads a firmware program from Flash Memory IC7002
with the data bus interface.

= Technical Tip =
It can be judged whether IC9001 is in the wake-up mode or in the sleep mode by checking the output voltage at pin-37 [VSTBY] of IC9001. (TEST Point: TP9018)
During sleep mode: 2.8[V] (BG1 voltage)
During wake-up mode: 3.0[V] (LDO2 (3.0V) voltage)
During sleep mode: 2.8[V] (BG1 voltage)
During wake-up mode: 3.0[V] (LDO2 (3.0V) voltage)
