Table 40. Interrupt Control Registers
The Crimzon
The interrupts are maskable and prioritized (see
divided as follows: three sources are claimed by Port 3 lines P33:P31, two by the counter/
timers and one for low-voltage detection. P32 and the UART receiver share the same
interrupt. Only one interrupt can be selected as a source. When the UART receiver is
enabled P32 is no longer used as an interrupt source. The UART transmit interrupt and
UART baud rate interrupt use the same interrupt as the P33 interrupt. You must select the
source that triggers the interrupt. When bit 7 of UTCL is 1, the UART transmit interrupt is
the source. When bit 7 of UCTL is 0 and bit 5 of UCTL is 1, the BRG interrupt is selected.
The Interrupt Mask Register (globally or individually) enables or disables the six interrupt
requests.
The source for IRQ1 is determined by bit 1 of the Port 3 Mode Register (P3M) and bit 4 of
the SMR4 register. If P3M[1]=0 (DIGITAL mode) and SMR4[4]=0, pin P33 is the IRQ1
source. If P3M[1]=1 (ANALOG mode) or SMR4[4]=1 (SMR interrupt enabled), the out-
put of the Stop Mode Recovery source logic is used as the source for the interrupt. See
