5.7.3.4 8-Bit Expanded Mode
MC68HC16Y3/916Y3
USER’S MANUAL
The SCIM2 uses an 8-bit data bus when BERR = 1 and DATA1 = 1 during reset. In
this configuration, pins DATA[7:0] are configured as port H, an 8-bit I/O port. Pins
DATA[15:8] are configured as data bus pins, and ADDR[18:3] are configured as
address bus pins. The alternate functions for these address and data bus pins as ports
A, B, and G are unavailable. ADDR[23:19]/CS[10:6] are configured as chip selects.
ADDR[2:0] are configured as address bus pins. Emulator mode is always disabled.
DATA8 determines the function of the DSACK[1:0], DS, AS, and SIZ[1:0] pins. If
DATA8 is held low during reset, these pins are used for discrete I/O (port E).
DATA9 determines the function of interrupt request pins (IRQ[7:1]) and the clock mode
select pin (MODCLK). When DATA9 is held low during reset, these pins are used for
discrete I/O (port F).
Table 5-18 summarizes pin function selections for 8-bit data bus operation.
NOTES:
ADDR23/CS10/ECLK
1. These pins have only one reset configuration in 8-bit expanded mode.
