72 / 189 page  Serial channels ST10F272Z2 72/189 Note: The deviation errors given in the Table 41 and Table 42 are rounded. To avoid deviation errors use a Baud rate crystal (providing a multiple of the ASC0 sampling frequency). 15.3 ASCx in synchronous mode In synchronous mode, data is transmitted or received synchronously to a shift clock which is generated by the ST10F272Z2. Half-duplex communication up to 8M Baud (at 40 MHz of fCPU) is possible in this mode. Table 42. ASC asynchronous baud rates by reload value and deviation errors (fCPU = 64 MHz) S0BRS = ‘0’, fCPU = 64 MHz S0BRS = ‘1’, fCPU = 64 MHz Baud Rate (Baud) Deviation Error Reload Value (hex) Baud Rate (Baud) Deviation Error Reload Value (hex) 2 000 000 0.0% / 0.0% 0000 / 0000 1 333 333 0.0% / 0.0% 0000 / 0000 112 000 +1.5% / -7.0% 0010 / 0011 112 000 +6.3% / -7.0% 000A / 000B 56 000 +1.5% / -3.0% 0022 / 0023 56 000 +6.3% / -0.8% 0016 / 0017 38 400 +1.7% / -1.4% 0033 / 0034 38 400 +3.3% / -1.4% 0021 / 0022 19 200 +0.2% / -1.4% 0067 / 0068 19 200 +0.9% / -1.4% 0044 / 0045 9 600 +0.2% / -0.6% 00CF / 00D0 9 600 +0.9% / -0.2% 0089 / 008A 4 800 +0.2% / -0.2% 019F / 01A0 4 800 +0.4% / -0.2% 0114 / 0115 2 400 +0.2% / 0.0% 0340 / 0341 2 400 +0.1% / -0.2% 022A / 015B 1 200 0.1% / 0.0% 0681 / 0682 1 200 +0.1% / -0.1% 0456 / 0457 600 0.0% / 0.0% 0D04 / 0D05 600 +0.1% / 0.0% 08AD / 08AE 300 0.0% / 0.0% 1A09 / 1A0A 300 0.0% / 0.0% 115B / 115C 245 0.0% / 0.0% 1FE2 / 1FE3 163 0.0% / 0.0% 1FF2 / 1FF3 Table 43.
