Bit 10
External EEPROM Enable (Read-only, it reflects status of the SDA pin upon reset)
0 = Disable
1 = Enable
Bit 9
External Microcontroller Enable (Read-only, it reflects status of the EXTMCU pin)
0 = Disable
1 = Enable
Bit 8
USB Transceiver (It reflects status of the INTXTR pin upon reset)
0 = External transceiver
1 = Internal transceiver
Bits 7-6
Reserved
Bit 5
Fast Serial Bus Write Enable
0 = Disable, serial bus outputs (SDATA and SCLK) are controlled by CR01_1-0
1 = Enable, serial bus outputs (SDATA and SCLK) are controlled by CR06 - CR09. Once
CR09 is programmed, all 32-bit data for SDATA and 32-bit data for SCLK from CR06 -
CR09 will be serially output in 400 Khz bit frequency (2.5 us bit time).
Bit 4
Serial Data Enable/Serial Data Strobe
0 = SDE#/SDS pin is driven low
1 = SDE#/SDS pin is driven high
Bit 3
Serial Interface Data Read (Read only)
0 = SDATA is low
1 = SDATA is high
Bit 2
Serial Interface Clock Read (Read only)
0 = SCLK is low
1 = SCLK is high
Bit 1
Serial Interface Data Write
0 = SDATA pin is driven low
1 = SDATA pin is tri-stated
Bit 0
Serial Interface Clock Write
0 = SCLK pin is driven low
1 = SCLK pin is tri-state
