Figure 3.6.1 shows an example of how to connect external memory to the
This example connects ROM and SRAM in 16-bit width.
By resetting, TMP92CM22 function as output port. Output latch of P82 (
When set port 8 from port function to CS function, set need bit of P8FC register
TMP92CM22
) are set to “1”, and output “H”.
latch of P82 is “0” (P8<P82> = 0). (P8FC<P82F> = 1)
If set function register (P8FC<P82F> = 1) after set output latch of P82 to “1”
(P8<P82> = 1), maybe don’t read ROM data during changing from port
function to
