NOTES:
CONTROL INTERFACES
When operated in MCU mode, MC145572 has two configurations that provide MCU access to its inter-
nal register set. The SPC mode is a four–wire serial interface that clocks data into or out of MC145572
at data rates up to 4 Mbps. This interface is compatible with National’s MICROWIRE
PCP mode configures MC145572 to have an eight–bit parallel data port that can be located anywhere
in processor memory. The PCP mode is enabled when the MCU/GCI pin is tied to a 1 and the PAR/SER
pin is tied to a 1. The SCP mode is enabled when the MCU/GCI pin is tied to a 1 and the PAR/SER
pin is tied to a 0.
Pin No.
PLCC
1. In NT mode, IN1 and IN2 carry PS1 and PS2 data.
2. DISS is OR’d into this output.
3. When IDL2 interface is operating in GCI electrical mode, this pin is named FSC.
4. When IDL2 interface is operating in GCI electrical mode, this pin is unused.
5. SFAX is muxed onto this pin.
6. 20.48 MHz, SFAR, and TSEN are muxed onto this pin.
7. DCHCLK and TxOFF are muxed onto this pin.
8. DCH in and TxMAG are muxed onto this pin.
9. DCH out and TxSIGN are muxed onto this pin.

When MC145572 is configured for MCU operation, it is possible to put the IDL2 interface
pins into GCI Electrical mode, which accepts GCI timing for transfer of 2B+D data only.
This is done by setting bit OR6(b3) GCI Mode Enable. Access to the MC145572 register
set is via the SCP or PCP. In GCI Electrical mode, the pin names and functions for IDL2
interface pins correspond to the GCI names and function.
