Status and IEnable Registers
The status and interrupt enable registers occupy the
same address space. The IER/SR bit in control reg-
ister 1 selects whether the status registers
(IER/SR = 0) or the IEnable registers (IER/SR = 1)
occupy addresses 0 and 1. Upon power-up, the con-
trol and IEnable registers contain all zeros; there-
fore, the status registers are visible and all
interrupts are disabled. The IER/SR bit must be set
to make the IEnable registers visible.
Status register 1 (SR1), shown in Figure 6, reports
all the conditions that can generate a low pulse four
SCLK cycles wide on the interrupt pin (INT). The
three least significant bits, FLAG2-FLAG0, are
used to monitor the ram buffer. These bits continu-
ally change and indicate the position of the buffer
pointer which points to the buffer memory location
currently being written. Each flag has a corre-
sponding interrupt enable bit in IEnable register 1
which, when set, allows a transition on the flag to
generate a pulse on the interrupt pin. FLAG0 and
FLAG1 cause interrupts on both edges whereas
FLAG2 causes an interrupt on the rising edge only.
Further information, including timing, on the flags
can be found in the Buffer Memory section.
The
next
five
bits;
ERF,
SLIP,
CCHG,
CRCE/CRC1, and CSDIF/CRC2, are latches
which are set when their corresponding conditions
occur, and are reset when SR1 is read. Interrupt
