USER’S MANUAL
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: data_sgpiod[0:31] (32 pins)
Data Bus – Provides the general purpose data path between the chip and all other
devices. Although the data path is a maximum of 32 bits wide, it can be sized to sup-
port 8-, 16-, or 32-bit transfers. DATA[0] is the MSB of the data bus.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: irq0_b_sgpioc0
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU. IRQ0 is a nonmaskable
interrupt (NMI).
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: irq1_b_rsv_b_sgpioc1
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
Reservation – This line used together with the address bus to indicate that the internal
core initiated a transfer as a result of a STWCX or a LWARX instruction.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Pin Name: irq2_b_cr_b_sgpioc2_mts
Interrupt Request – One of the eight external lines that can request, by means of the
internal interrupt controller, a service routine from the RCPU.
Cancel Reservation – Instructs the chip to clear its reservation, some other master
has touched its reserved space. An external bus snooper would assert this signal.
SGPIO – This function allows the pins to be used as general purpose inputs/outputs.
Memory Transfer Start – This pin is the transfer start signal from the MPC555 /
MPC556 memory controller to allow external memory access by an external bus mas-
ter.
Pin Name: irq3_b_kr_b_retry_b_sgpioc3
