There are two low-power operating modes for Z90356: SLEEP mode and STOP mode.
In SLEEP mode, the controller uses the 32.768-KHz clock for the SCLK to reduce power
consumption.
In STOP mode, the processor is suspended, and the power consumption is minimized.
User control can be monitored either through the keypad scanning port or the 16-bit
remote control capture register.
Two input/output port blocks are available for general-purpose digital I/O application.
Each port bit can be programmed to be either an input or output port. To conserve the
device pin count, some port pins are mapped to provide I/O to the ADC converter block
2
and I
C interface block.
The 25 configurable I/O pins are general-purpose pins for functions such as serial data
2
I/O, LED control, key scanning, power control and monitoring, and I
C serial data
communications.
Port 0 and 1 directions are defined in R6(0) and R7(0), respectively. R4(0) and
R5(0) are data registers for both Ports 0 and 1. Figure 10, Figure 11, and Figure 12
indicate I/O configuration and sharing with other functional units.
