5 / 24 page LCD Controller 5 /24 Issue date: 13 August, 1999 Syntek Semiconductor Co., Ltd. STK55C324 4 : = 0 CPU clock is system clock. = 1 CPU clock is 32.768K Hz. 7-5 : Reserved. The default values for each bit is zero. 1003 IRQ flag register. Read & write. Read function : Bit 0 : = 1 Fix-time timer interrupt, IRQ1. 1 : = 1 Timer interrupt, IRQ2. 2 : = 1 External interrupt, IRQ3. Write function : Bit 0 : = 0 Clear fix-time timer interrupt. 1 : = 0 Clear timer interrupt. 2 : = 0 Clear external interrupt. * Before firmware exits the interrupt routine, the interrupt flag must be cleared. Otherwise, the IC will get into interrupt again. * Write 0 to clear the corresponding IRQ but do not use ‘STZ $1003’ to clear all interrupts at the same time. Following instructions are recommended LDA $1003 STA IRQBuff EOR #0FFH STA $1003 ;Clear all active interrupts at the same time LDA IRQBuff AND #1 BEQ next_irq * Do NOT use TRB to test and clear this register. Following instructions are recommended. LDA $1003 AND #1 ;Check IRQ 1 BEQ next_irq STA $1003 ;Clear the active interrupt. 1004 Port 1 data. Read & write. 1005 Set port 1 bit function. Write only. * An '1' in this register will set the corresponding pin of port 1 as an output pin. * The default values for each bit is zero. A pull-up resistor can be added to the pin by code option. |
