This bit is the protected bit. It means programming this needs to write “59h”, “16h”, “88h” to
address 0x5000_0100 to disable register protection. Reference the register REGWRPROT
at address GCR_BA+0x100.
00 = Clock source from external crystal clock. (4 ~ 24MHz)
01 = Reserved
10 = Clock source from HCLK/2048 clock
11 = Clock source from internal 10 kHz oscillator clock
