MC68HC16Y1TS/D
3.8.4 Port G
Port G is available in single-chip mode only. In single-chip mode, these pins are always configured for
general-purpose I/O.
This register can be read or written anytime the MCU is not in emulator mode.
The bits in this register control the direction of the pin drivers when the pins are configured as I/O. Any
bit in this register set to one configures the corresponding pin as an output. Any bit in this register
cleared to zero configures the corresponding pin as an input.
3.8.5 Port H
Port H is available in single-chip and 8-bit expanded modes only. The function of these pins is deter-
mined by operating mode — there is no pin assignment register associated with this port.
This register can be read or written anytime the MCU is not in emulator mode. Reset has no effect.
The bits in this register control the direction of the pin drivers when the pins are configured as I/O. Any
bit in this register set to one configures the corresponding pin as an output. Any bit in this register
cleared to zero configures the corresponding pin as an input.
3.9 Chip Selects
Typical microcontrollers require additional hardware to provide external chip select signals. The
MC68HC16Y1 includes nine programmable chip select circuits that can provide 2 to 13 clock cycle ac-
cess to external memory and peripherals. Two additional chip selects CSE and CSM provide emulator
support. Address block sizes of 2 Kbytes to 1 Mbyte can be selected. However, because ADDR[23:20]
= ADDR19 in the CPU16, 512-Kbyte blocks are the largest usable size.
