BIT 1 MOTOR ENABLE 1
Active high status of the MTR1 disk interface output pin. This bit is low after a hardware reset and unaffected by a
software reset.
BIT 2 WRITE GATE
Active high status of the WGATE disk interface output.
BIT 3 READ DATA TOGGLE
Every inactive edge of the RDATA input causes this bit to change state.
BIT 4 WRITE DATA TOGGLE
Every inactive edge of the WDATA input causes this bit to change state.
BIT 5 DRIVE SELECT 0
Reflects the status of the Drive Select 0 bit of the DOR (address 3F2 bit 0). This bit is cleared after a hardware reset
and it is unaffected by a software reset.
BIT 6 RESERVED
Always read as a logic "1".
BIT 7 RESERVED
Always read as a logic "1".
PS/2 Model 30 Mode
BIT 0 nDRIVE SELECT 2
The DS2 disk interface is not supported.
BIT 1 nDRIVE SELECT 3
The DS3 disk interface is not supported.
BIT 2 WRITE GATE
Active high status of the latched WGATE output signal. This bit is latched by the active going edge of WGATE and is
cleared by the read of the DIR register.
BIT 3 READ DATA
Active high status of the latched RDATA output signal. This bit is latched by the inactive going edge of RDATA and is
cleared by the read of the DIR register.
BIT 4 WRITE DATA
Active high status of the latched WDATA output signal. This bit is latched by the inactive going edge of WDATA and is
cleared by the read of the DIR register. This bit is not gated with WGATE.
BIT 5 nDRIVE SELECT 0
Active low status of the DS0 disk interface output.
BIT 6 nDRIVE SELECT 1
Active low status of the DS1 disk interface output.
BIT 7 nDRV2
