16 / 38 page  16 06/19/2000 GL600USB/GL600USB-A/GL600USB-B Revision 1.3 Value on POR: “- - 0 - - 0 0 0” INDAR: (Address 04h/84h, Indirect address register) R/W R/W R/W R/W R/W R/W R/W R/W INDAR7 INDAR6 INDAR5 INDAR4 INDAR3 INDAR2 INDAR1 INDAR0 Any instruction using the INDF register actually accesses the register pointed by the INDAR register. Value on POR: “x x x x x x x x” [1] Note 1: “x” means unknown PORT1 (Address 06h, Port 1 data register) R/W R/W R/W R/W R/W PORT1.4 PORT1.3 PORT1.2 PORT1.1 PORT1.0 PORT1 is a 5-bits latch for Port 1.0~Port 1.4. Reading the PORT1 register gets the status of the pins. Writing to it will write to the port latch. All write operations are read-modify-write operations. PORT1CON is used to enable/disable every bits of the port latch. Value on POR: “- - - x x x x x” PORT2 (Address 07h, Port 2 data register) R/W R/W R/W R/W R/W R/W R/W R/W PORT2.7 PORT2.6 PORT2.5 PORT2.4 PORT2.3 PORT2.2 PORT2.1 PORT2.0 PORT2 is an 8-bits latch for Port 2.0~Port 2.7. Reading the PORT2 register reads the status of the pins. Writing to it will write to the port latch. All write operations are read-modify-write operations. PORT2CON is used to enable/disable every bits of the port latch. Value on POR: “x x x x x x x x” PCHBUF (Address 0Ah/8Ah, Write buffer of Program Counter’s bit 10-8) R/W R/W R/W PCHBUF2 PCHBUF1 PCHBUF0 Write buffer for upper 3-bits of Program Counter. The upper byte of Program Counter is not directly accessible. PCHBUF is a holding register for the PC[10:8] that are transferred to the upper byte of the Program Counter when branch occur. Please see PCL register to get more detail information. Value on POR: “- - - - - 0 0 0” INTEN (Address 0Bh/8Bh, Interrupt enable register) R/W R/W R/W GIE TMROEN TMROF GIE: Global interrupt enable bit 1: Enable all interrupts 0: Disable all interrupts TMROEN: Timer overflow interrupt enable bit 1: Enable timer interrupt 0: Disable timer interrupt TMROF: Timer overflow interrupt flag bit. This bit should be cleared to ‘0’ by firmware after it is set by hardware. 1: Timer register has overflowed 0: Timer register did not overflow Value on POR: “0 - 0 - - 0 - -“ PHVAL (Address 0Dh, Photo-sensor value register) R/O R/O R/O R/O PHVAL3 PHVAL2 PHVAL1 PHVAL0 PHVAL[3:0]: the 8 channel, 4 bits analog-to-digital converter data. The ADC input is select by PHSEL register from Port 2.0~Port 2.7 |
